RECALL: The function $y=f(x)+c$ involves a vertical shift of $c$ upward of the parent function $f(x)$ when $c \gt 0$. The given function is in the same format as the equation above, and has $c=3$. This means that the graph of $y=x^2+3$ involves a vertical shift of $3$ units upward 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 3 units upward. (Refer to the blue graph in the attached image above.) (Refer to the attached image in the answer part above for the graph.)
