We know,
1 unit : 5 feet

so, 120 ft = (120 / 5) units
                = 24 units
  
        75 ft = (75 / 5) units

Nesterboy [21]

Answer:

No

Step-by-step explanation:

To obtain the inverse function

let y = f(x) and rearrange making x the subject, that is

y = 3x + 1 ( subtract 1 from both sides )

y - 1 = 3x ( divide both sides by 3 )

\frac{y-1}{3} = x

Change y back into terms of x, thus

f^{-1}(x) = \frac{x-1}{3}
