Neveah has created the function f(x) = the quantity of 2x plus 4, divided by 3 to represent the growth of her hair, where x represents the number of months since her last hair cut. Neveah discovers that using the inverse function to solve for x = 6, she can predict when her hair will have grown 6 inches. Explain to Neveah how to accomplish this, using complete sentences.

Question

you know if she can just get the "telly savalas" haircut, she wouldn't have to bother with an inverse function =)

Hahah, very true. Why does Neveah have to be so difficult? lol (:

jdoe0001 · Answer

$\bf f(x)=\color{red}{y}=\cfrac{2x+4}{3}\qquad inverse\implies x=\cfrac{2\color{red}{y}+4}{3}$
notice all you have to do is swap the variables

then just solve for "y"
