Question 984318
<font face="Times New Roman" size="+2">


If you are having difficulty with these, then you are over-thinking the problem.  These are nothing more than a fancy way to express an arithmetic problem.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ 5x\ -\ 1]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(-1)\ =\ 5(-1)\ -\ 1]


in general, for the given function


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(a)\ =\ 5a\ -\ 1]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\left(\text{The artist formerly known as Prince}\right)\ =\ 5\left(\text{The artist formerly known as Prince}\right)\ -\ 1]


Get the idea?
