Simplify the rational expression. If the rational expression cannot be simplified, so state. \( \frac{4 y-20}{3 y-15} \) Select the correct choice below and fill in any answer boxes in your choice. A. \( \frac{4 y-20}{3 y-15}=\square \) B. The expression cannot be simplified.

If \( f(x)=\left\{\begin{array}{ll}2 x-5 & \text { if }-2 \leq x \leq 4 \\ x^{3}-4 & \text { if } 4<x \leq 5\end{array}\right. \), find: (a) \( f(0) \), (b) \( f(1),(c) f(4) \), and \( (d) f(5) \). (a) \( f(0)=\square \) (b) \( f(1)=\square \) (c) \( f(4)=\square \) (d) \( f(5)=\square \)
