How do I find the inverse of the function f(x) = 3(3x+4)

1 Answer

so f(x) is equal to them saying y = 3(3x+4)

here is an example of how to solve an inverse function

f(x)=3(3x+4) x=93

switch x and y which will give you this

x = 3(3y+4)

substitute 93 in for x

93=3(3y+4)

then solve

93=9y+12

subtract 12 from both sides which will give you

81=9y

then divide by 9 on both sides to get

9=y
