fill out the information for the function:

Question

f(x)=cos(pi/4(x+pi/6))-3

phase shift:

vertical shift:

amplitude:

period:

Answer 1

The general form is:

f(x) = A·cos(B(x-C)) + D

1. A = amplitude
2. B = 2π/period (you know B, so solve for the period))
3. C = phase (horizontal) shift
4. D = vertical shift

Can you figure it out?
