Answer:
option A is the correct choice
Step-by-step explanation:
The trigonometric equation you are using has a general form
y = A* tan w*(x - r)
Where
A is the amplitude of the function
w is the frequency rad/s
r is the phase shift
In your case
A = 2
B = w = 3
r = pi/2
y = 2* tan 3*(x - pi/2)
Answer:
Linear equation is 
Step-by-step explanation:
We have,
Total monthly income (in dollars) = y
Number of times an app is opened = x
As, the advertiser pays $0.002 each time an app is opened.
So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.
Since, $30 per month is also paid by the advertiser.
Thus, total monthly income 'y' is given by,

Hence, the graph of the linear equation is given below.
