Question

Identify the key features for the following equation: y=4sin(x)−5What kind of cyclic model is the equation?

Answer 1

Given,

The equation of the function is:

`y=4sinx-5`

The standard equation of wave is,

`y=Asin\text{ \lparen Bx+C\rparen+D}`

Here, A is the amplitude

B is the period.

C is the phase shift.

D is vertical shift.

As the given function have the sine function so, the cyclic model of the wave is sine.

Amplitude = 4.

Midline = -5

Minimum = -9

Hence, the key feature of the cyclic model is identified.
