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

Answer:

- 2 and 4

Step-by-step 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
