Let's plug in x = 2.
f(x) = x^2
f(2) = 2^2 ... replace every x with 2
f(2) = 4
----------
Now plug in x = 3.
f(x) = x^2
f(3) = 3^2 ... replace every x with 3
f(3) = 9
-----------
And x = 5 as well.
f(x) = x^2
f(5) = 5^2 .... replace every x with 5
f(5) = 25
-----------
We see that
f(2)+f(3) = 4+9 = 13
which is not equal to f(5) = 25.
So f(2)+f(3) = f(5) is false.
------------
Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.
If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.

F A taxicab company charges $2.80 plus $0.40 per mile. Carmen paid a fare of $8.80. Enter and solve an equation to find the number of miles she traveled. Use m as your variable.
Answers
Answer:
15 miles
Step-by-step explanation:
8.80-2.80=6
6/0.40=15 miles
m = miles traveled.
$2.80 + $0.40m = $8.80
Subtract $2.80 from both sides.
$0.40m = $6.00
Divide both sides by $0.40
m = 15
Carmen traveled a total of 15 miles.

B. The function is always positive.
C. The function is positive when x < 0 and when x > 0.
D. The function is positive when x > 0.
Answers
Answer:
The correct option is;
D. The function is positive when x > 0
Step-by-step explanation:
The reciprocal parent function is of the form;
[tex]y = \dfrac{a}{x - h} + k[/tex]
Where;
h = The horizontal translation
k = The vertical translation
a = The orientation of the graph
Therefore, whereby we have, h = 0, k = 0. and a = 1, the equation becomes;
[tex]y = \dfrac{1}{x - 0} + 0 = \dfrac{1}{x}[/tex]
Therefore, the value of the function y is positive when x > 0 and is negative when x < 0.

Answer:
Any value of m, except when m = -12.7, will make the expression equal to 6.35
Step-by-step explanation:
The equation you are given is:
6.35 = 12.7 + m / m + 12.7
First you need to know the rule that anything divided by itself will equal 1.
So no matter what number you use to substitute for m it will equal one because both the top and bottom of the division sign are the same. Except if you use negative 12.7 or a to high of a negative which will cause it to equal -1 which multiplied by 6.35 would equal -6.35

if f(x) = -x^2+4x-9 and g(x) = x - 8 find g(f(-1)).
Answers
Answer: g(f(-1))=-22
Step-by-step explanation:
To find g(f(-1)), you want to first want to solve f(-1). Once you solved that, you plig the answer you get into g(x). Then, you will have your final answer.
f(-1)=-(-1)²+4(-1)-9 [exponent]
f(-1)=-1+4(-1)-9 [multiply]
f(-1)=-1-4-9 [subtract from left to right]
f(-1)=-14
We have found that f(-1)=-14. Now, we know in -14 into g(x) and solve.
g(-14)=(-14)-8 [subtract]
g(-14)=-22
Now, we know that g(f(-1))=-22.
