Question

For what values of x does f(x)=0 A. -1, 1, 2 B. -2, -1, 1 C. -3, -1, 1D. -1, 1, 3

Answer 1

Solution

At the point where f(x)=0 , the graph crosses the x-axis .

All points where f(x)=0 denotes the points where the graph intersects the x-axis. This points includes

$\begin{gathered} x=1 \\ x=-1 \\ x=-3 \end{gathered}$

Hence the right choice is OPTION C
