To find the stationary point, we first differentiate \(f(x)\) with respect to \(x\):
\(f'(x) = \frac{d}{dx}[8 - (x - 2)^2] = -2(x - 2)\)
Set the derivative equal to zero to find the stationary point:
\(-2(x - 2) = 0\)
Solving for \(x\), we get:
\(x = 2\)
Substitute \(x = 2\) back into the original function to find the \(y\)-coordinate:
\(f(2) = 8 - (2 - 2)^2 = 8\)
Thus, the coordinates of the stationary point are \((2, 8)\).
To determine the nature of the stationary point, consider the second derivative:
\(f''(x) = \frac{d}{dx}[-2(x - 2)] = -2\)
Since \(f''(x) < 0\), the stationary point at \((2, 8)\) is a maximum.
