Answer:
1. 9-2=7
2. -6-(-4)=-2
Step-by-step explanation:
a=9
b=2
c=-6
d=-4
b-3
-1-3
-4
is the correct answer
option A is the correct choice
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)
