The time period and amplitude of the given function are 4 and 3.5 respectively. Then the correct option is C.
What is wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The time period of the given function will be
Time period = 4
And the amplitude of the function will be
[tex]A = \dfrac{5+2}{2} = 3.5[/tex]
