Math Problem Statement
For x ≥ 0, the functions f(x) = 2x - 6 and g(x) = (2√x / 3) + 7 are given. Find g⁻¹(x).
Solution
Let's solve this step by step.
The function is given as:
We need to find the inverse function .
Steps to Find :
-
Replace with :
-
Swap and (to reflect the inverse relationship):
-
Solve for :
-
Subtract 7 from both sides:
-
Multiply through by 3:
-
Divide by 2:
-
Square both sides to remove the square root:
-
Thus, the inverse function is:
