Answer:
the last one (bottom right)
Step-by-step explanation:
4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2
so, we only need to look, where the function reaches -2.
it should be at x = 0, x = 0.5 and x = 1.
5x + 5/4 = x - 3/9
5•x + 5/4 = x - 3/9
144x = -57
x = -19
48
≈ -0.395833
