Question

Determine where f(x) = g(x) from the graph.

A. x = -2 ; x = 2

B. x = -2 ; x = 0 ; x = 2

C. x = 0 ; x = -8

D. x = 0 ; x = 2

Answer 1

The correct answer is B

Explanation:

To find this, we simply look for the values on the x-axis where the lines cross. They cross at (-2, 0), (0, -8) and (2, 0). So, the 3 x values would be -2, 0 and 2

Answer 2

x = -2, x = 0 and x = 2.

B is the correct option.

Explanation:

We have to find where f(x) = g(x) from the graph.

In order to find the same, we see where the functions f(x) and g(x) intersects each other.

The x-coordinate of the intersection of the both graphs is the required solution.

From the given graph the functions f(x) and g(x) intersect each other at (-2,0), (0,-8) and (2,0).

Therefore, the values of x where f(x) = g(x) are x = -2, x = 0 and x = 2.

B is the correct option.
