Answer:
x = - 2 , x = 2 are the input values
Explanation:
g(x) = 4 , means y has the value of 4 and we want to find the values of x corresponding to this.
locate y = 4 on the y- axis , then a horizontal line through this point , intersects the graph at (- 2, 4 ) and (2, 4 )
thus when g(x) = 4 , the input values are x = - 2 and x = 2
