All but first for every single x gives single y so the second, third and fourth are function

At first for x=2 we have two y (2 or -2) so this isn't function.

Answer:

Assume x is directly proportional to y :

$y \: \alpha \: x \\ y = kx$

when y is 9, x is 2:

substitute to find value of k :

$9 = (k \times 2) \\ k = \frac{9}{2}$

Therefore, equation is:

${ \boxed{ \boxed{2y = 9 x}}}$

Replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

f(x)=x-1
y=x-1
x=y-1
x+1=y
x+1=f⁻¹(x)
f⁻¹(x)=x+1
