(a) One value of x for which h(x) = 0
We have h(x) = 0 when the line crosses the horizontal axis. From the graph, we see that it happens when we have x = 1.
(b) h(0)
The expression h(0) is the value of the function when x = 0. From the graph, we see that we have h(0) = 2.
Answer(a) One value of x for which h(x) = 0 : 1
(b) h(0) = 2
