Step 1:

\

The functions are $\"\"$ and $\"\"$ .

\

The function $\"\"$ .

\

Compare the function with $\"\"$ .

\

$\"\"$ and $\"\"$ .

\

Amplitude : $\"\"$ .

\

Period : $\"\"$ .

\

Construct the table of values in the interval $\"\"$ :

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\

Step 3:

\

Graph the functions $\"\"$ and $\"\"$ on the same plane :

\

(1) Draw the coordinate plane.

\

(2) plot the points.

\

(3) connect the points to a smooth curve.
