Answer:
amplitude = 3
period = π/2
phase shift: x = -π/4
Step-by-step explanation:
Given:
f(x) = −3 cos(4x + π) + 6
which has the general form:
f(x) = A cos(Bx - C) + D
with:
A = -3
B = 4
C = -π
D = 6
The amplitude, period and phase shift is calculated as follows:
amplitude = |A| = |-3| = 3
period = 2*π/|B| = 2*π/|4| = π/2
phase shift: C/B = -π/4
z=t and y = 4y -- 6 for any t?
Ok so I made up a fraction 7/5
! The result can be shown in multiple forms.
