Answer:
Step-by-step explanation:
The given equation is y=3x+9.
To find the inverse of the function we switch x and y then solve for y .This will give us the inverse of the function.
Switching x and y in the given equation we have :
x=3y+9.
Adding 9 both sides :
x-9=3y.
With y term 3 is multiplied .Dividing both sides by 3 we have:
\(\frac{x}{3} -3=y\)
Or \(y=\frac{1}{3} x-3\)
