Answer:

Step-by-step explanation:

y intercept is when x = 0
So, Putting x = 0 in the above function
=> f(0) = 
=> f(0) = 2*1
=> f(0) = 2
So, y-intercept is (0,2)
Answer: 1
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = Cos(2x)
Inverses for trig functions are found the same way as any other inverse. The trick is to interchange x and y.
x = cos(2y) Take the inverse cos of both sides.
cos-1(x) = 2y Divide by 2
1/2 cos-1(x) = y
