Well first you need to find how many feet are in 6yd
The inverse of this function is f(x) = ![\frac{3x + 15}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%20%2B%2015%7D%7B4%7D%20%20)
To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.
f(x) =
----> Switch the x and f(x)
x =
----> Muliply both sides by 3
3x = -15 + 4f(x) ----> Add 15 to both sides
3x + 15 = 4f(x) ----> Divide both sides by 4.
f(x) = ![\frac{3x + 15}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%20%2B%2015%7D%7B4%7D%20%20)
C. Is the answer.. because A- can't be a whole number so x that out. integer can't have a decimal x that out. rational number are like square roots and so. so c is the best answer.
