Answer
Refer to the blue graph below.
Work Step by Step
RECALL:
(1) The function $y=-f(x)$ involves a reflection about the x-axis of the parent function $f(x)$.
(2) The function $y=a\cdot f(x)$ involves a vertical stretch of the parent function $f(x)$ when $a \gt 1$. The function will involve a vertical compression when $0 \lt a \lt 1$.
The parent function of the given function is $y=|x|$.
The graph of the given function involves a vertical stretch by a factor of $3$ of the parent function $y=|x|$.
Thus, to graph the given function:
(1) Graph the parent function $y=|x|$ .
(Refer to the red graph in the attached image below)
(2) Multiply $3$ to each y-value of the parent function while keeping the value of the x-coordinate of each point.
(Refer to the blue graph in the attached image above.)
