At an amusement park, a person spends $30 on admission and food, and then goes on number of rides that cost $2 each.
I
a. Write an equation to represent the total amount A spent
at the amusement park if a person goes on anywhere from 0 to
5 rides.
b. Represent the relation as a table, as a graph, and as a mapping
diagram
c. Find the domain and range, and then determine whether the
relation is a function or not.

a, A= $30 + $2x

x could be 0 - 5

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
