Solution Steps

Step 1: Find the derivative of $f(x)$

The derivative of $f(x)$ is $f'(x) = 5 - 2 x$.

Step 2: Solve $f'(x) = 0$

The critical points are found by solving $f'(x) = 0$. The solutions are \left\{\frac{5}{2}\right\}.

Step 3: Determine the nature of each critical point

At $x = \frac{5}{2}$, the function has a relative maximum.

Step 4: Find the value of $f(x)$ at each relative extremum

At $x = \frac{5}{2}$, $f(x) = 4.25$.

Final Answer:

The function has a relative maximum at $x = \frac{5}{2}$, with $f(x) = 4.25$.
