h(3x)=9x3

Explanation:

Since h(x) changes to h(3x), you have to change all the x values in the equation to 3x.

h(3x)=3(3x)3
h(3x)=9x3

So the answer is

h(3x)=9x3

h(3x)=9x3

Explanation:

When we evaluate the function h at the value 3x, we replace all of the instances of x in the original expression with 3x. Doing that, we get:

h(x)=3(3x)3
h(x)=9x3
