\

The function is $\"\"$

\

Find the domain.

\

$\"\"$

\

31)

\

Convert $\"\"$ into radians.

\

Convert from degrees to radians multiply by $\"\"$

\

$\"\"$

\

Option 3 is correct answer.

\

35)

\

The value of $\"\"$

\

Find angle $\"\"$

\

$\"\"$

\

The value of $\"\"$

37)

\

Observe the graph;

\

The graph is represents the sinsoidal wave form.

\

Since the graph of the function is $\"\"$

\

Graph the domain is $\"\"$

\

Range is $\"\"$

\

The sine wave is across x-axis negative to positive leads.

\

The function is $\"\"$

Since the graph of the function is $\"\"$

\

The graph is origin starts from y axis at 2.

\

Graph the domain is $\"\"$

\

Range is $\"\"$

\

The sine wave is across x-axis negative to positive leads.
