97)

Observe the graph,

The sinu soidal function begins negative half cycle to positive half cycle completed.

Oone cycle is completed

Since, the graph the  function is

False.

98)

Observe the graph,

The sinu soidal function begins negative half cycle to positive half cycle completed.

One cycle is completed

Domain is

Range is

The wave form shifted vertical four units down.

Since, the graph the function is

Option 4 is correct answer.

99)

Observe the graph,

The sinu soidal function begins negative half cycle to positive half cycle completed.

Domain is

Range is

The wave form shifted vertical one units down and streatched by factor of 2 units cos function.

Since, the graph the function is

Option 1 is correct answer.
