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.

A) 8; the number of elephants in the herd
B)one eighth; the number of elephants in the herd
C)8; the elephants' rate in miles per hour
D)one eighth; the elephants' rate in miles per hour

Answer 1

C is correct i got the answer right on my test :)

Answer 2

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

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
