Question

The function f(x) = 4x + 8 represents the distance traveled by a herd of elephants in miles. The function g(x) = x − 1 represents the time the herd traveled in hours. Solve f divided by g of 4, and interpret the answer.

Answer 1

Answer:C) 8; The elephants’ rate in miles per hour

Step-by-step explanation:

First write the question as an equation that can be solved to give you a numerical answer.

[f(4)=4(4)+8] / [g(4)=(4)-1]

Then solve the equation.

24/3=8

Finally use background information to give you the context.

Since the problem gives you the function for distance and the function for time then it can be concluded that the context will be the elephants’ rate in miles per hour

Explanation:

Answer 2

`(f/g)(4)=8`

Interpretation: 4 elephants traveled at a speed of 8 miles per hour

Explanation:

Given

`f(x) = 4x + 8`

`g(x) = x -1`

Required

`(f/g)(4)`

This is calculated as:

`(f/g)(4)=(f(4))/(g(4))`

We have:

`f(x) = 4x + 8`

`f(4) = 4 * 4 + 8 =24`

`g(x) = x -1`

`g(4) = 4 - 1 = 3`

So:

`(f/g)(4)=(f(4))/(g(4))`

`(f/g)(4)=(24)/(3)`

`(f/g)(4)=8`
