Question

Explain how the graph of the function below could be used to determine the solution to the corresponding quadratic

Answer 1

To get the real solutions of the quadratic equation from the graph of the equation, we must determine the x-intercepts of the graph.

In this case, the x-intercepts of the graph are:

`\begin{gathered} (-4,0), \\ (0.5,0)\text{.} \end{gathered}`

Therefore, the solutions of the quadratic function are:

`x=-4\text{ and x=0.5.}`
