Answer:
option-B
Step-by-step explanation:
Time Period:
we know that
time period is the time after which value starts repeating it's value
we can see that
time period is 120
[tex]T=120[/tex]
Mid-line:
maximum value is 5
so, max=5
minimum value is -1
so, min=-1
[tex]M=\frac{max+min}{2}[/tex]
now, we can plug values
[tex]M=\frac{5-1}{2}[/tex]
[tex]M=2[/tex]
Amplitude:
maximum value is 5
so, max=5
minimum value is -1
so, min=-1
[tex]A=\frac{max-min}{2}[/tex]
now, we can plug values
[tex]A=\frac{5+1}{2}[/tex]
[tex]A=3[/tex]
so, option-B
