Find the Inverse of f(x) = 3x -18

y = 1/3x+6

Step-by-step explanation:

Step 1

- Rewrite f(x) as y

f(x) = 3x-18 => y = 3x-18

Step 2

- Swap x and y

y = 3x-18 => x = 3y-18

Step 3

-  Slove for y (By that it means isolate y)

x = 3y-18 (+18 both sides)

x+18 = 3y (Then divide both sides by 3)

1/3x+6 = y

Final

y = 1/3x+6

1/3

Step-by-step explanation:

There are 6 numbers on a dice, you want one out of the 2 outcomes, so tat makes it 2/6 or 1/3 chance of rolling a 3, or a 5
