RECALL: (1) The function $y=f(x-h)$ involves a horizontal shift of $h$ units to the right of the parent function $f(x)$ when $h\gt0$. The function involves a horizontal shift of $|h|$ units to the left when $h \lt0$. (2) The function $y=f(x)+c$ involves a vertical shift of $c$ units upward of the parent function $f(x)$ when $c \gt 0$. The function will involve a vertical shift of $|c|$ units downward when $c \lt 0$. The parent function of the given function is $y=\sqrt{x}$. The given function can be written $y=f(x+4)-3$ where $f(x)$ is the parent function. Thus, the graph of the given function involves (i) a horizontal shift of $3$ units to the left, and (2) a vertical shift of $3$ units downward of the parent function $y=\sqrt{x}$. Therefore, to graph the given function: (1) Graph the parent function $y=\sqrt{x}$ . (Refer to the red graph in the attached image below) (2) Shift the graph of the parent function 4 units to the left. (Refer to the orange graph in the attached image below.) (3) Shift the graph in Step (2) 3 units downward. (Refer to the blue graph in the attached image in the answer part above)
