Answer:
Choice D). is correct.
Step-by-step explanation:
Given function graph is sinusoidal so let's compare with formula
We know that amplitude is the height from the center line to the peak (or to the trough). From graph we can see that height from the center line to the peak is 20
So amplitude A=20
In that formula, period is given by
From graph we see that period is
So both must be equal
cross multiplying them gives
B=4
Clearly there is no shift so C and D are 0
Now plug these values into formula
Hence choice D is correct.
