A rational function $f$ is given. Find all values of a for which $f(a)$ is the indicated value. $$ f(x)=\frac{x-5}{x+1} ; f(a)=\frac{3}{5} $$
Use the given rational function to find the indicated function values. If a function value does not exist, so state. $$ f(x)=\frac{x^{2}-3 x-4}{3-x} ; f(-1), f(3), f(5) $$
