Question

The graph of a function h is shown below. Find one value of x for which h(x) = 0 and find h(0) .

Answer 1

Explanation

(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
