What is Domain and Range of a Function ?Domain is the value that can be an input to the function and the range is all the value a function can obtain.
From the given graphs ,
For Graph 1
It can be seen that the line extends from x = -5 to +4
where -5 is not included
therefore the domain is given by
D = { x| -5 < x ≤4}
and the range is
R = {y | -3 < y≤4}
For Graph 2
The input value x extends from -∞ to +∞
so the domain is
D = { x| - ∞ ≤ x ≤ +∞ }
and the range is given by
R = {y | - ∞ ≤ y ≤ 3}

The figure showing the construction is given below.
Steps for the construction of a circle through three points not on a straight line are as follows:
1. To create two lines, connect the points.
2. Create the line's perpendicular bisector.
3. Create the opposite line's perpendicular bisector.
4. The circle's center is where they intersect.
5. Draw your circle by placing the compass on the center point and adjusting its length to reach any point.
What happens if the points are parallel?
The circle traveling through all three points will have an infinite radius if the three points are collinear, or all situated on a straight line. Therefore, a practical circle cannot traverse three collinear locations. The two radii would be parallel and would never come together at a center if you tried the construction. We may claim that they do cross mathematically but at infinity.
Hence, after following the steps we obtain the circle.

Jaime makes the following claim.
An angle with a measure of π/3 radians in a circle with a radius of 3 inches is smaller than an angle with a measure of π/3 radians in a circle with a radius of 6 inches. This is because the radian measure is based on the length of the radius of the circle and a radius of 3 inches is smaller than a radius of 6 inches.
1. Review Jaime’s statement and what you know about angles and radians.
a. Explain whether you agree with Jaime’s statement or not.
b. Provide examples to support your whether you agree or disagree.
Answers
In the case above, Jaime claim is true.
The explanation to agree with Jaime’s statement or not is that the longer the length of the radius, the longer the length of the arc.What is the claim about?1. Note that radian measure:
= [tex]\frac{60° }{360°}[/tex] x 2π x 3
= 1/6 x 6π
= π
2. Note that radian measure:
= [tex]\frac{60° }{360°}[/tex] x 2π x 6
= 1/6 x 2π x 6
=2π
So we can write it as:
π/3 x 180°/π = 60°
Therefore, via the solution above, Jaime claim is true.
3. Note that: Radian measures: the percentage of arc measures x 2π x radius and so one can say that The explanation to agree with Jaime’s statement or not is that the longer the length of the radius, the longer the length of the arc.

f(x)=12(x-10)2+18
What is the "a" value of this function?
Answers
Answer:
12
Step-by-step explanation:
Assuming that the 2 actually represents square, the equation is
[tex]f(x) = 12(x-2)^2 + 18[/tex]
[tex](x-2)^2 = x^2 - 4x + 4\\\\12(x-2)^2 + 18 = 12( x^2 - 4x + 4) + 18 = 12x^2 -48x + 48 + 18 = 12x^2 -48x + 66\\[/tex]
This equation is of the form
[tex]ax^2 + bx + c[/tex]
[tex]a = 12, b = -48, c = 66[/tex]
Note
Since the question is only asking for the a value which is the coefficient of x² it is clear that 12 is the coefficient without expanding (x-2)² but it is always better to proceed as above in case you are asked for b and c values also
Value of the function at x=a is [tex]12a^{2} -240a +1218[/tex].
Given function f(x)=[tex]12(x-10)^{2} +18[/tex]
We have to find the value of function at x=a.
For this we have to just put x=a in the function f(x)=[tex]12(x-10)^{2}+18[/tex]
f(a)=12[tex](a-10)^{2} +18[/tex]
we have to expand (x-10) to the power 2 to get the value of function.
f(a)=[tex]12(a^{2} +10^{2} -20a)+18[/tex]
=[tex]12a^{2}+1200-240a+18\\[/tex]
=[tex]12a^{2} -240a+1218[/tex]
Hence the value of function at x=a is [tex]12a^{2} -240a+1218[/tex] means f(a)=[tex]12a^{2} -240a+1218[/tex].

A man of height 1.5 m is standing in front of a tower of height 81.5 m. At what angle should he observe the top of the tower from the distance of 80 m?
Answers
The angle at which the man should observe is 45 degrees.
To solve the question :Given :
height of man = 1.5m
height of tower = 81.5 m
distance between tower and man = 80 m
Since, ABCD is a rectangle, AD = BC = 80m
Similarly, AB = CD = 1.5m
EC = ED + CD
81.5 = ED + 1.5
ED = 80m
Now, in order to find the angle EAD, we use trigonometric functions,
tan ∅ = perpendicular / base = ED / AD
tan ∅ = 80 /80 = 1
∅ = [tex]tan^{-1} (1)[/tex]
∅ = 45°.

Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 8 a.m., in which interval will their systolic pressure be lowest?
Answers
Based on the graph, the interval will their systolic pressure be lowest is 4pm to 5pm.

The domain and range of function f(x) = 2x - 41 is domain (-∞,∞) and range is (0,∞).
What is a function?A relation is a function if it has only One y-value for each x-value.
The domain of a function is the set of values that we are allowed to plug into our function.
This set is the x values in a function such as f(x).
The range of a function is the set of values that the function assumes.
The function f(x) = 2x - 41 is a linear function.
As a linear function, the domain is all real numbers, and the range is also all real numbers.
So the domain is (-∞,∞) and range is (0,∞)
Hence, the domain and range of function f(x) = 2x - 41 is domain (-∞,∞) and range is (0,∞).
