Question

What are the solutions to the equation f(x)=g(x)?

A) x= -3, 4
B) x= -4, 2.5
C) x= -0.8, 2.5
D) x= 8, -8

Answer 1

B

Explanation:

The points where f(x) intersects g(x) are - 4 and 2.5. These points are the solution of the equation f(x)=g(x)

Answer 2

(-4,8) and ( 2.5, -8)

Explanation:

The solutions are where the two graphs intersect

They intersect at x = -4 and y = 8 and at x = 2.5 and y = -8

(-4,8) and ( 2.5, -8)
