Solution:
We have,
The steps of finding the inverse function are:
Step 1: Substitute .
Step 2: Interchange x and y.
Step 3: Taking square on both sides, we get
Step 4: Adding 21 on both sides, we get
Step 5: Divide both sides by 7.
Step 6: Substitute .
, where
.
Therefore, the inverse of the given function is and the arrangement of steps is shown above.
The solution of the equation (√x-8) + 2 = 7 is x = 13.
According to the given question.
We have an equation
Since, we solve the above equation for x .
Therefore,
⇒ (√x - 8) = 7 - 2
⇒ (√x - 8) = 5
Squarring both the sides.
⇒ x - 8 = 5
⇒ x = 5 + 8
⇒ x = 13
Hence, the solution of the equation (√x-8) + 2 = 7 is x = 13.
