Question

(a) plot a point for each of the zeros of $f(x)$.

Explanation:

Step1: Identify zeros on graph

Zeros of $f(x)$ are where the graph crosses the $x$-axis ($y=0$). From the graph, these occur at $x=-4$ and $x=2$.

Step2: Plot the zero points

The points are $(-4, 0)$ and $(2, 0)$.

Answer:

The zeros are plotted at the points $(-4, 0)$ and $(2, 0)$ on the coordinate grid.
