Work Step by Step

RECALL: The function $y=f(x)-c$ involves a vertical shift of $c$ downward of the parent function $f(x)$ when $c \gt 0$. The given function is in the same format as the equation above, and has $c=4$. This means that the graph of $y=x^2-4$ involves a vertical shift of $4$ units downward of the parent function $y=x^2$ Thus, to graph the given function: (1) Graph the parent function $y=x^2$ . (Refer to the red graph in the attached image below) (2) Shift the parent function 4 units downward. (Refer to the blue graph in the attached image above.)
