a. -1

b. 2

Step-by-step explanation:

When the x value of g(x) is 1, the y value can be visibly seen to be -1. When the y value of g(x) is 0, the only x value which can be seen to satisfy this condition is x=2. Hope this helps!

1. -1

2. 2

Step-by-step explanation:

g(1) is the point on the graph where the x-coordinate is 1. Looking at the graph, we trace the point where x = 1 and see that on the line at x = 1, y is equal to -1. So, g(1) = -1.

g(x) = 0 when the line crosses the x-axis. Looking at the graph, we see that the line crosses the x-axis at the point (2, 0). This means that the x-coordinate is 2. So, one value of x for which g(x) = 0 is 2.

Hope this helps!
