1. Graph the function f(x)=2 sin x-2 (Graph 1)

2. Graph the function f(x)= - cos (2x) + 1 (Graph 2)

Explanation:

The function is

To plot the function in the graph, first we shall determine the amplitude, period, phase shift and vertical shift.

The function is of the form,

where A is the amplitude =

Period is ,

Phase shift is C,

Vertical shift is D.

Hence, from the function , we have,

Amplitude =

Period =

Phase shift = 0

Vertical shift = -2

Now, substituting the values for x, we get the corresponding values for y.

Now, we shall graph the function

Similarly, we shall determine the amplitude, period, phase shift and vertical shift.

Amplitude =

Period =

Phase shift = 0

Vertical shift = 1

Now, substituting the values for x, we get the corresponding values for y in the function

Hence, plotting these points we get the graph which is attached below:

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
