We are tasked with finding the absolute maximum and minimum of the function:

$f(x) = (x - 3)^{\frac{4}{5}} - 3$

on the interval $[0, 5]$. Let's break this down step by step.

1. Domain of the Function

The given function involves a fractional exponent, so we need to ensure that the expression $(x - 3)^{\frac{4}{5}}$ is well-defined. Since the exponent $\frac{4}{5}$ is positive, this expression is defined for all $x \geq 3$. However, for $x < 3$, the function is still real because fractional powers with even numerators (like $\frac{4}{5}$) still produce real results.

2. Critical Points (First Derivative Test)

To find critical points, we'll compute the derivative $f'(x)$ and set it equal to zero. However, based on the form of the function, it's important to focus on how the function behaves near $x = 3$ and at the endpoints of the interval $[0, 5]$.

Evaluate at Key Points

We’ll evaluate $f(x)$ at the endpoints of the interval and check for any critical points within the interval.

• $f(0) = (0 - 3)^{\frac{4}{5}} - 3 = (-3)^{\frac{4}{5}} - 3 = 3^{\frac{4}{5}} - 3$
• $f(5) = (5 - 3)^{\frac{4}{5}} - 3 = 2^{\frac{4}{5}} - 3$

Next, we determine the behavior at $x = 3$, which is where the base of the power becomes zero:

• $f(3) = (3 - 3)^{\frac{4}{5}} - 3 = 0 - 3 = -3$

3. Compare Values

After evaluating the function at critical points and endpoints, compare the values to find the absolute maximum and minimum.
