The graph below shows a function $y = f(x)\text{.}$ Moving the slider allows you to also graph $y = a\cdot f(x)\text{,}$ where you can change the value of $a$ between $0$ and $3\text{.}$

• Move the slider so $a > 1\text{,}$ and use what you observe to complete the statement below:
  To graph $y = af(x)$ when $a > 1\text{,}$ you would begin with $y = f(x)$ and ? stretch it away from compress it toward the $x$-axis.
• Now, move the slider so that $0 < a < 1\text{,}$ and use what you observe to complete the statement below:
  To graph $y = af(x)$ when $0 < a < 1\text{,}$ you would begin with $y = f(x)$ and ? stretch it away from compress it toward the $x$-axis.
