Find the inverse of:

a. To sketch f(x), we use the graph of the parent function

Translated 3 units to the left:
b. The part of the function f(x) that is one-to-one and non-decreasing is in the domain [-3, ∞). Expressing in inequality notation: x ≥ -3.
c. The function f(x) can be written as:

Applying square root on both sides:

Solving for x:

Swapping letters:

Since we have chosen only the non-negative part of the domain for f(x), we use only the positive sign:

Both functions, f(x) and its inverse are shown below:
