h(3x) = -9x - 3

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) = -9x - 3

So the answer is

h(3x) = -9x - 3

h(3x)=-9x-3

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)=-9x-3
