Question

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 3

so find inverse function do thise steps:
replace f(x) with y

Answer 4

then switch sides of x and y

Answer 5

solve for y

Answer 6

write as f^-1(x) instead of y

Answer 7

1. Substitute f(x) with y.
2. Reverse the x and y variables.
3. Solve for y.
4. Replace y with f (x).

Answer 8

so

6 = (2y + 4) / 3

Answer 9

yeah

Answer 10

solve for y now

Answer 11

6 = 3(2y + 4) ?

Answer 12

no

Answer 13

18==2y+4

Answer 14

y=7

Answer 15

when x=6 y=7

Answer 16

how did u do that tho ?

Answer 17

Answer 18

nvm. i got it. thanks

Answer 19

ok
