Solution

The correct response is ℎ𝑥=9·3𝑥.

Here's why:

The function ℎ𝑥=3𝑥+2 is a horizontal translation of the function 𝑓𝑥=3𝑥, meaning it shifts the graph of 𝑓𝑥 horizontally on the 𝑥𝑦-plane.

To express ℎ as a vertical dilation of 𝑓, we need to multiply 𝑓 by a constant. In this case, the constant is 3, because the function ℎ is obtained by adding 2 to each value of 𝑓.

So, if we multiply 𝑓 by 3, we get 3·𝑓𝑥=3·3𝑥=9·3𝑥, which is equivalent to ℎ𝑥.

Therefore, ℎ𝑥=9·3𝑥 is the correct response.
