Hey I need a second opinion to see if my formulas and calculations are correct. Also I need help with graphing this problem.
My problem is to find amplitude, period, horizontal shift, vertical translation, step and then graph of:
y= 2 - (1/3) cos ( πx + (3π/2) ) , -1/4 ≤ x ≤ 15/4
Using the formula:
y = A cos ( Bx + C) + D
A = 2
B = π
C = 3/2
D = 0
Amplitude: |A| = 1/3
Period: ((2π) / |B|) = 2
Horizontal Shift: -C/B = (3/(2π))
Vertical Translation: D = 0
Step: ((2π)/2)/B = 1
