explain what a,h, and k do to transform the parent absolute function y=|x| to the function y= a|x|…
Answers
The a ,h and k values affect the parent absolute function ,by altering the the size , causing horizontal and vertical movements respectively.
How do the a , h and k values affect the function?a )a values
a values affect the size of the graphed parent absolute function and they have a scalar factor.When a is greater than 1 , we have a vertical stretch (Taller appearance )and a horizontal compression (Thinner appearance).When a is between 0 and 1 , we have a vertical compression( Shorter appearance) and a horizontal stretch ( wider appearance).b ) h values
h values cause left or right movement of the graph, which is known as the horizontal shift or translation.When h is negative, the graph moves right.When h is positive , the graph moves left.c ) k values
k values cause up and down movement ,which is known as the vertical shift or translation.When k is negative, the graph moves down.When k is positive , the graph moves up.To learn more about parent absolute function, refer:

What is Linear approximation ?
A linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations.
The formula is
L(x) = f(a) + f'(a) (x - a)
Given,
y = sin(2x)
Δx = 0.1 at x = 0
y'(x) = dy/dx = 2 cos 2x
As, x = 0
y'(0) = 2 cos 0
we know, cos 0 = 1
y'(0) = 2
Δy = y'(x) * Δx
= y'(0) * Δx
= 2 * 0.1
Δy = 0.2 (Approx value)
Exact value of Δy = sin(2 * 0.1) - sin 0
= sin(0.2) - 0
= 0.19867
% error = [ (Exact value - Approx value) / Exact value ] * 100
= [ (0.2 - 0.19867) / 0.19867 ] * 100
= 0.66945 or 0.67%
Hence, the percentage error is 0.67%

find the value of b/a if a+1/b-1=5/1 and a-1/b+1=1/1
Answers
Answer:
1/2
Step-by-step explanation:
You want the value of b/a when (a+1)/(b-1)=5/1 and (a-1)/(b+1)=1/1.
SolutionThe latter equation tells you ...
a -1 = b +1
b = a -2
Then the first equation tells you ...
a +1 = 5(b -1)
a +1 = 5(a -2 -1) substitute for b
a +1 = 5a -15 . . . . eliminate parentheses
16 = 4a . . . . . . . . add 15 -a
4 = a . . . . . . . . . divide by 4
b = a -2 = 4 -2 = 2 . . . . find the value of b
b/a = 2/4 . . . . . . . . . . find the desired ratio
b/a = 1/2
