Answer 1

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

$T=120$

Mid-line:

maximum value is 5

so, max=5

minimum value is -1

so, min=-1

$M=\frac{max+min}{2}$

now, we can plug values

$M=\frac{5-1}{2}$

$M=2$

Amplitude:

maximum value is 5

so, max=5

minimum value is -1

so, min=-1

$A=\frac{max-min}{2}$

now, we can plug values

$A=\frac{5+1}{2}$

$A=3$

so, option-B
