Pablo 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) = 20n + 3 , where 2 ≤ n ≤ 6

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

It varies from 2 to 6.

It varies from 43 to 123.

It varies from 40 to 120.

It varies from 2 to 123.

My answer is It varies from 2 to 6.

Am I right? :)

n = 2 is the smallest allowed value for n, agreed?

anonymous · Answer

Agreed

jim_thompson5910 · Answer

so the smallest value in the range is the result after plugging in n = 2
