Question

What i the inverse of f(x)= 6x-9

Answer 1

g(x)=(x+9)/6

Answer 2

what saubhik said

function says multiply by 6, subtract 9.
so inverse says add 9, divide by 6.

Answer 3

usually written as "inverse"
\[f^{-1}(x)=\frac{x+9}{6}\]

Answer 4

if ƒ is a function from a set A to a set B, then the inverse of ƒ is a function from B to A, with the property that a round trip from A to B to A (via a composition of ƒ and its inverse) returns each element of A to itself. if g be inverse function of f, we have g(f(x))=x for every x in domain of f.

Answer 5

in a line, If ƒ maps X to Y, then g maps Y back to X. (g is inverse of f)

Answer 6

(9+x)/6
