Work Step by Step

RECALL: The graph of the equation $f(x)=k$ is a horizontal line whose y-intercept is $(0, k)$. Every point on the line has a y-coordinate of $k$. Thus, the graph of the equation $f(x)=3$ is a horizontal line and every point on the line has a y-coordinate of $3$. This means the following points are on the line: $(-3, 3)$ and $(3. 3)$. Plot the two points above and connect them using a straight line. (Refer to the graph in the answer part above.)
