Question

Use the graph of the function y = -x² + 2x + 8 to

determine the solutions of the quadratic equation
0 = -x²+2x+8.
What are the solutions of the quadratic equation
0 = -x²+2x+8?
O-4 and 2
O-2 and 8
O-2 and 4
O4 and 8

Answer 1

- 2 and 4

Explanation:

the solutions to the quadratic equation are the values of x on the x- axis where the graph crosses.

the graph crosses the x- axis at x = - 2 and x = 4

then solutions are - 2 and 4

Answer 2

-2 and 4

Explanation:

Hello!

The solutions to a quadratic function can be found by finding the values of x when y is 0.

If you are given a graph, you can find the roots of the quadratic by looking at where the graph intersects the x-axis (y = 0).

Given this graph, the graph intersects the x-axis at 2 spots:

• -2
• 4

Therefore, the solutions for the quadratic are -2 and 4.
