Answer:
cos 4x
Step-by-step explanation:
Because this graph begins at (0, 1), we immediately suspect that it's a cosine function. Additionally, since there are 4 cycles of this cosine function between x = 0 and x = 2pi, we suspect horizontal compression:
252 inches squared is the answer
+
38.1%
Divide 165 by 433
165/433 = 0.381
Multiply the answer by 100
0.381 x 100 = 38.1
