ANSWER
C.
EXPLANATION
The given function has range:
-3≤f(t)≤3
This implies that, the amplitude is
The function is symmetric with respect to the origin so this is a sine function.
This function is again reflected in the x-axis, hence
a=-3.
The period of this function is
This implies that, b=3,
hence the equation of the function is
