Someone please help me out!!! A sinusoidal function repeats itself every 40 seconds, has a maximum
height of 10 m, and a minimum height of 6 m. At time t=0, the function's
height is at its maximum value. *
A) f(x) = 2 sin(9x) + 6
B) f(x) = 2 sin(9x) + 8
C) f(x) = 2 cos(9x) + 8
D) f(x) = 2 cos(9x) + 6

The graph shows the function f(x) = (2.5)x was horizontally translated left by a value of h to get the function g(x) = (2.5)x–h.

Asap! i'm not good math and i'm lost.
