CPM Homework Help : CCA2 Problem 1-117

Sketch a few different equilateral triangles. Create multiple representations ( $x→y$ table, graph, equation) of the function with inputs that are the length of one side of an equilateral triangle and outputs that are its perimeter.

Hint:

Start by creating some equilateral triangles of different sizes.

More Help 1:

Use the triangles you drew to make a table.

More Help 2:

Draw the graph.

More Help 3:

Use the table of the graph to help you write the equation.

Show:

$\left. \begin{array} { | c | c | } \hline 1 & { 3 } \\ \hline 2 & { 6 } \\ \hline 3 & { 9 } \\ \hline 4 & { 12 } \\ \hline 5 & { 15 } \\ \hline 6 & { 18 } \\ \hline \end{array} \right.$

First quadrant graph, with increasing line, passes through origin, & the point (1, comma 3), which is labeled, p of, 1 = 3.
