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))
HINT ;- x intercept is the point where graph crosses x axis .So the point lies on x-axis (i.e y = 0)
Step 1: find x.
Make y = 0
Step 2: find y in g(x)
g(x) at x = 1 i.e g(1) (= 0)
So, the coordinates of x intercept are (1, g(1)).
