Answer:
Option C is correct
Step-by-step explanation:
Given the expression
[tex]\frac{y}{x^2}=5[/tex]
We have to describe the variation.
[tex]Expression:\frac{y}{x^2}=5[/tex]
[tex]y=5x^2[/tex]
[tex]y=cx^2[/tex] where c is equals to 5
[tex]y \propto x^2[/tex]
which shows y varies directly as the square of x.
Option C is correct
