Answer to Problem 5E
The domain and range of h is [-3,4] and [-1,4], respectively.
Explanation of Solution
Given information: the graph of function h is provided,
Graph:
Interpretation:
The domain of the function h is all the ix-values of the points on the graph, and the range is all the corresponding y -values.
From the graph of h , we see that the domain of h is the interval [-3, 4] and the range of h is the interval [-1, 4].
Hence, the domain and range of h is [-3,4] and [-1,4], respectively.
c.
To calculate: the value of x for which h ( x ) = 3
c.
Answer to Problem 5E
the value of x for which h ( x ) = 3 is
Explanation of Solution
Given information: the graph of function h is provided,
Graph:
Calculation:
The function value of h ( a ) from the graph of h , is the height of the graph above the x -axis at x = a ,
Therefore, h ( x ) = 3 is the x -value on the x -axis where the height above it is 3, that are,
Hence, the value of x for which h ( x ) = 3 is

Explanation of Solution
Given information: the graph of function h is provided,
Calculation:
When
Therefore, the x-values from the graph for
Hence, the values of x for
