b.

To determine

To calculate: the domain and the range from the graph

Expert Solution

Answer to Problem 10E

the domain from the graph is [,] and the range from the graph is [,] .

Explanation of Solution

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

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.3, Problem 10E , 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.

Since, the graph obtained in part a. is straight line and has infinite number of x and y values the domain is [,] and the range is [,]

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