Answer:
Step-by-step explanation:
The standardized cosine function is ;
Amplitude |A| = 2
Period
2π = 4B
Midline y = 4; D = 4
Phase shift; since no phase shift is given; then C = 0
The cosine function:
5 * 5 = 25 and 6 * 6 = 36 :)
32 is between 5 * 5 = 25
and also between 6 * 6 = 36
those are both perfect squares
i hope this helps
