You add 1/6 to both sides
Step-by-step explanation:
The answer is 2.5 because the point is on -1.5, so -1.5+4=2.5
Answer:
C. -8
This is the correct answer. Hope this helps :)
Answer:
option C is the correct answer
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
The frequency is
w = (2*pi)/period
period = pi/4
w = 8
r = -pi/2
y = -2* cos 8*(x + pi/2)
