The required function when the parent function is stretched comes to be .
The parent function is:
If a function f(x) is vertically translated by k units f(x) becomes f(x)+k where k is positive.
Given function is vertically shifted by 4 units
So, f(x) will become f(x)+4
So, the required function is
Therefore, the required function when the parent function is stretched comes to be .

Given:
Consider the below figure attached with this question.
∠EFH = (5x + 1)°, ∠HFG = 62°, and ∠EFG = (18x + 11)°
To find:
The measure of ∠EFH.
Solution:
From the figure it is clear that ∠EFG is divide in two parts ∠EFH and ∠HFG. So,
Isolate variable terms.
Divide both sides by 13.
The value of x is 4.
Therefore, the measure of ∠EFH is 21°.
