Question

12. For a sinusoidal function in the form y = A sin Bx + C or
y = A cos Bx + C, the period is 2, the maximum is 10, the equation of the midline is y = 3, the y-intercept is 3, and A < 0.

What is the equation of the function?


(Points : 3)
y = –7 sin (πx) + 3
y = –13 sin (πx) + 3
y = –7 cos (πx) + 3
y = –13 cos (πx) + 3

Answer 1

Period = 2π/B
Midline = C

Answer 2

A = ½(max - min)

Answer 3

Actually, you don't have the minimum so, A = max - midline

Answer 4

thank a lot for the for the help
