Question

Kyle is reading a book. He reads 71 pages per hour. Write a function that represents the number of pages he reads. Be sure to indicate any domain restrictions.

Answer 1

The function that represents the number of pages he reads is f(x) = 71x, x ≥ 0

Writing a function that represents the number of pages he reads.

From the question, we have the following parameters that can be used in our computation:

Rate = 71 pages per hour

Using the above as a guide, we have the following:

f(x) = 71x

Where,

x is the number of hours

Also, we have the domain to be

x ≥ 0

Hence, the function is f(x) = 71x

Answer 2

Let x represent the number of hours Kyle spends reading

The function f(x) that would represent the number of pages Kyle reads given that he reads 71 pages per hour would be:

`f(x)\text{ = 71x}`

The domain is the set of allowable x-values. For this problem, x represents the number of hours and it cannot be negative hence, the domain is:

`\text{ Domain : }\ge\text{ 0}`

Answer Summary

The function f(x):

`f(x)\text{ = 71x}`

Domain: greater than or equal to zero
