Question

Given f(x) = the quantity of x plus 4, divided by 6, solve for f-1(7).

Answer 1

\[f(x)=\frac{ x+4 }{ 6 }\]

Answer 2

solve for f^-1(7).

Answer 6

Can you find the inverse function? solve this for x (rearrange to get x=...)
\[\large y=\frac{ x+4 }{ 6 }\]

Answer 7

x(y)=2(3y-2) ?

Answer 8

@helpme1.2 this one.

Answer 9

You didn't need to factor it at all... x = 6y - 4 is fine. Now swap x and y.

SO f^-1(x) = 6x - 4

Answer 10

And find r f^-1(7)

Answer 11

38...?

Answer 12

i'm guessing that's it? xD

Answer 13

if 6*7 - 4 is 38 then yes that's it :P
