According to the graph of the function, it is found that:
a) h(2) = 1.
b) h(x) = -3 when x = -4.
What is h(2)?
Looking at the graph, h(2) is given by the value of y when x = 2, that is, the value of the vertical axis when the horizontal axis is of 2. Hence, h(2) = 1.
What is the value of x for which h(x) = -3?
Looking at the graph, it is given by x when y = -3, that is, the value of the horizontal axis when the vertical axis is of -3, hence, h(x) = -3 when x = -4.
