b.

To determine

the domain and the range from the graph

Expert Solution

Answer to Problem 16E

The domain from the graph is [5,5] and the range from the graph is [5,0] .

Explanation of Solution

Given information: consider the graph obtained in part a.,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.3, Problem 16E , additional homework tip  2

Calculation:

The domain of the function f is all the x-values of the points on the graph, and the range is all the corresponding y -values.

From the graph, the function cuts the y -axis at y=5 and covers the graph till 0, therefore, the range is [5,0] . The function covers the graph from x=5 to x=5 , therefore, the domain is [5,5]

Hence, the domain from the graph is [5,5] and the range from the graph is [5,0] .
