Question

$f(x) = pm a|x - h| - k$ what effect does \h\ have on the graph?

1. the graph up or

up if negative
down if positive.

1. shifts the graph left or right. left if positive and right if negative.
2. shifts the graph up or down. up if positive and down if negative.
3. shifts the graph left or right. right if positive and left if negative.

Explanation:

For the absolute value function $f(x) = \pm a|x - h| - k$, the parameter $h$ controls horizontal shifts of the parent function $f(x)=|x|$. When $h$ is positive, the graph shifts right by $h$ units; when $h$ is negative, the expression becomes $|x - (-|h|)| = |x + |h||$, which shifts the graph left by $|h|$ units.

Answer:

Shifts the graph left or right. Right if positive and left if negative.
