Question
g(x) = 2x - 2
The function g is defined by the equation above. Which of the following points in the xy-plane is an x-intercept of the graph of the equation y = g(x)?
- (-1, g(-1))
- (0, g(0))
- (1, g(1))
- (2, g(2))
The correct answer is: (1, g(1))
The x-intercept of g(x) = 2x - 2 is the value of x when g(x) = 0
0 = 2x - 2
2x = 2
2x = 21
x = 1
(1, g(1))
