Answer:
Explanation:
EX. in function f(x) = 2 cos x -2
The first 2 is your amplitute, how high from middle line it goes
the last 2 is the shift in y direction.
For f(x) = 2 cos x -2 (see image for this function)
it has been shifted down 2 and has a period
At
your function has a solution of -4
The first blank is f(x) = cos x+2
Second blank is f(x) = cos x -2
