Answer:
22.1 or 22
Step-by-step explanation:
Y + 1 varies√x
Y + 1 = K√x ( k is costant)
so we solve for K
given: 14 + 1 = K√27
15 = K√27
divide both sides by √27
15/√27 = K
to find the value of y
y + 1 = 15/√27 (8) : substitute K for 15/√27
Y + 1 = 120/√27
i.e Y = 120/√27 - 1
Y = 23.1 - 1
Y = 22.1 or 22
For this case, we must find the inverse of the following function:

We follow the steps below:
We exchange the variables:

We put the variable y on the left side of the equation:

We apply logarithm properties:

So:
