Question

Use the graph to estimate the roots of the equation.

Answer 1

The roots of a function are the points where the graph crosses the x-axis.

Thus, in the following graph, we can see that the function has 2 roots. These are in:

`\begin{gathered} x=-2 \\ \text{and} \\ x=2 \end{gathered}`

Answer:

x = -2

x = 2
