Please see attached 

Given the function \( f(x) = (x - 14)^2 \), \( x \leq 14 \):

**(a)** Find \( f^{-1}(x) \).

**(b)** Graph \( f \) and \( f^{-1} \) in the same rectangular coordinate system.

**(c)** Use interval notation to give the domain and the range of \( f \) and \( f^{-1} \).

**(a)** Find \( f^{-1}(x) \). Be sure to include any domain restrictions.

\[ f^{-1}(x) = \sqrt{x} + 14,\ x \geq 0 \]

**(b)** Choose the correct graph which shows \( f \) and \( f^{-1} \) graphed in the same coordinate system.

- Option A shows a graph with a parabola and a linear function.
- Option B shows a similar graph to A.
- Option C also displays a parabola and a linear line.
- Option D contains graph elements similar to others.

The correct graph must accurately reflect the parabolic shape of \( f(x) \) and the linear form of its inverse, with correct intersection points and symmetry about the line \( y = x \).

**Graph Analysis**:

- The parabola \( f(x) \) is represented as a U-shaped curve opening upwards.
- The linear function \( f^{-1}(x) \) should be reflected across the line \( y = x \).
- Each graph option shows different variations of these plots; select the one that correctly reflects the inverse relationship with the correct domain and range constraints.

The solution involves analyzing the symmetry and intersections between \( f(x) \) and \( f^{-1}(x) \).
