Solutions

Chapter 2, Problem 45RE
To determine

To find: Viewing rectangle from which we can draw appropriate graph of the function.

Expert Solution

Explanation of Solution

Given information:

A function f(x)=6x315x2+4x1

As given function is cubic function which is defined for all real value of x. So domain of function is set of all real values of x. Range of cubic function is also set of all real value. Hence we can write:

  Domainoff(x)(,)Rangeoff(x)(,)

Hence veiwing rectangle to draw appropiate graph of given function is [100,100]by[100,100] sbecause all given viewing rectangle lies in domain of function. Hence maximum viewing rectangle is [100,100]by[100,100] which is correct answer.

Interpretation:

Viewing rectangle for most appropriate graph is [100,100]by[100,100]
