Question

1. The equation y = -x2 - 2x + 8 is graphed on the
set of axes below.
у
→X
Based on this graph, what are the roots of the
equation -- x? - 2x + 8 = 0?
B. 2 and -4
A. 8 and o
D. 4 and -2
C. 9 and -1

Answer 1

Answer:

It B since The root is obtained when F(x)=0 and if F(x)=y this means y=0 and when you look art graph the y=0 presented in two points x=-4 and x=2
