Answer:
(a) x = 0
(b) g(2) = -5
Explanation:
Another way of representing g(x) is with the variable "y". In other words, the value of g(x) is the value on the y-axis (vertical axis).
(a) The question is asking you to give the "x" value when the line crosses y = -4. The only value which satisfies this is x = 0.
(b) When 2 is placed inside the parentheses of g(x), it is asking you to find the "y" value of the line at x = 2. The only value which satisfies this is y = -5.
