<span>cos 4x + cos 2x = 2 - 2 sin^2 2x - 2 sin^2 x
cos 4x + cos 2x = 1 + 1 − 2sin^2(2x) − 2sin^2(x)
cos 4x + cos 2x = (1 - 2sin^2(2x)) + (1 - 2 sin^2(x)
cos 4x + cos 2x = cos 4x + cos 2x</span>
Answer:
Linear: y = x, y = x/2 - 3, 3x + 2 = 12
Nonlinear: y = 6/x - 2, y = 3x^3 + 5
Step-by-step explanation:
Linear functions form straight lines while nonlinear functions do not.
