Question

Help with functions

Answer 1

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.

Answer 2

so you just need to get the inverse of \[f(x) = \frac{ 2x+4 }{ 3 }\]

Answer 3

remember to f(x) = y and when doing the inverse you replace x with y and y with x

Answer 4

thanks :)
