$\"\"$

The function is $\"\"$ .

(a)

Find the zeros of $\"\"$ on the interval $\"\"$ .

Find the zeros of $\"\"$ by equating $\"\"$ to zero.

$\"\"$

The general solution of $\"\"$ is $\"\"$ , where $\"\"$ is an integer.

$\"\"$ .

The general solutions is $\"\"$ , where $\"\"$ is an integer.

If $\"\"$ then $\"\"$ .

The solutions on the interval $\"\"$ are $\"\"$ .

Therefore, the zeros of $\"\"$ on the interval $\"\"$ are $\"\"$ .

(b)

The function is $\"\"$ and the interval is $\"\"$ .

Rewrite the function as $\"\"$ .

Make a table to find the ordered pairs.

Choose different values of $\"\"$ on the interval $\"\"$ , then find corresponding values for $\"\"$ .

Draw a coordinate plane.

Plot the intercpts and points obtained in the above table.

Connect those points with a smooth curve.

(c)

Solve $\"\"$ on the interval $\"\"$ .

$\"\"$

The general solution of $\"\"$ is $\"\"$ , where $\"\"$ is an integer.

$\"\"$

If $\"\"$ then $\"\"$ .

The solutions on the interval $\"\"$ are $\"\"$ .

Label the points on the graph of $\"\"$ .

$\"\"$

The points on the graph of $\"\"$ are $\"\"$ , $\"\"$ , $\"\"$ , $\"\"$ , $\"\"$ , and $\"\"$ .

(d)

Observe the graph drawn in part (b) along with the results of part (c) :
