In algebra, we learn about functions of various types. these functions are often seen in a progression from least complicated (linear) to most complicated (piecewise with nonlinear parts). and then there are other types of functions in-between: exponential, quadratic, polynomial, radical, and logarithmic. but with all their differences and unique properties, these share a common trait of being functions that we can graph in a coordinate plane. what are some other things you can observe to have that same quality of functions: unique, but sharing a common trait or purpose?

Following are some common traits that all the functions bear:

1) All the functions produce only one outcome for a given input. A function cannot produce more than one outcomes at a single input. In other words, for each value of x on its domain, function can will produce a distinct value of y.

2) Any vertical line drawn on the graph of a function will never meet the graph more than once.

3) A function cannot have more than one horizontal asymptotes. A function will have either no horizontal asymptote or just one asymptote.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
