Question

Carla is making ramps of different lengths. The ramps are made with rectangular and square wooden boards. The relationship between the length of the ramp in feet, f(n), and the number of square boards used, n, is represented by the function below.

f(n) = 4n + 5 , where 20 ≤ n ≤ 30

Which statement is correct about the range of the length of the ramp for the given domain?

It varies from 20 to 30.

It varies from 20 to 125.

It varies from 80 to 120.

It varies from 85 to 125.

Answer 1

plug in 20 and 30

Answer 2

Answer 3

to get range

Answer 4

I think you just have to plug in 20 and 30 into the function f(n) = 4n + 5

Answer 5

d. simply put lower and upper values of n in equation. . .

so the answer is d.

Answer 11

@theyatin No one really cares if you can do the work. That is not the point. The point is trying to get the asker to do it and by simply giving out the answer you do nothing in helping the asker. Point the asker asked which answer it was from your explanation.
