Question

the graph of a function f is shown. how many real zeros does f have?
real zeros.

Explanation:

Step1: Define real zeros of a function

A real zero of a function $f$ is an $x$-value where $f(x)=0$, which corresponds to where the graph intersects the $x$-axis.

Step2: Count x-axis intersections

Observe the graph: it crosses the $x$-axis at 3 distinct points.

Answer:

3 real zeros.
