To solve this problem you must apply the proccedure shown below:
1. You have the following parent function given in the problem above:
[tex] f(x)=x^{2} [/tex]
2. And you have the function [tex] g(x)=5(x^{2} ) [/tex]
3. By definition, if you have the function [tex] y=ax^{2} [/tex] and [tex] |a|>1 [/tex] it is a vertical stretch.
4. Therefore, you have that:
[tex] |a|=5\\ 5>1 [/tex]
Therefore the answer is: It is a vertical stretch.
