Question

question 15 (1 point) (02.05 lc) which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x)+4? a the graph shifts 4 units up. b the graph shifts 4 units down. c the graph shifts 4 units left. d the graph shifts 4 units right.

Explanation:

For a function $y = f(x)$, when we change it to $y=f(x)+k$ where $k>0$, the graph of the function shifts vertically. A positive $k$ value causes an upward shift. Here $k = 4$, so the graph of $f(x)$ shifts 4 units up.

Answer:

A. The graph shifts 4 units up.
