Notice that the graph on the picture represents the following function:
[tex]y=x^2[/tex]
now, we have the general rule for a transformation of a function:'
[tex]\begin{gathered} y=kf(x) \\ k>1\Rightarrow the\text{ graph gets compressed} \\ 0in this case, we have the following function:[tex]y=4x^2[/tex]
notice that the difference between this function and the parent function is the coefficient 4, which happens to be greater than 1, then , the graph of y = 4x^2 would be the following:
where the red graph represents y = 4x^2
