Question

What function best represents a sine function with an amplitude of 4, a period of pi over 6, and a midline at y = −2?

Answer 1

f(x) = −2 sin(x − pi over 6) + 4

f(x) = 4 sin 12x − 2

f(x) = 4 sin(x − pi over 6) − 2

f(x) = −2 sin 12x + 4

Answer 2

the amplitude is the coefficient of x

Answer 3

so 2nd or thid but im not sure sorry

Answer 4

Thanks, I'm going w/ the third one since it says " a period of pi over 6" in the problem
