Question

f(x) = 3x – 9; horizontal stretch by a factor of 6

Answer 1

Answer:

f(x)=0.5x-9

Explanation:

If we stretch f(x) by a factor of n, we have the following:

$y=f(\frac{1}{n}x)$

Therefore, stretching f(x) = 3x – 9 horizontally by a factor of 6 gives:

$\begin{gathered} f(x)=3(\frac{1}{6})x-9 \\ f(x)=0.5x-9 \end{gathered}$
