7. Identify a horizontal or vertical stretch or compression of the function f(x)=√x by observing the equation of the function g(
Effectus [21]

It is a vertical stretch.

<h3>What is functions?</h3>

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Given

To solve this problem you must apply the procedure shown below:

1. You have the following parent function given in the problem above:

f(x) = √x

2. And you have the function g(x) = √3x

3. By definition, if you have the function y = ax and |a| > 1 it is a vertical stretch.

4. Therefore, you have that:

|a| = √3

√3 > 1

Therefore the answer is: It is a vertical stretch.
