Answer:
C
Step-by-step explanation:
f"(x) < 0, which means the function is concave down at all values of x.
For any such function, within the domain of a ≤ x ≤ b, the secant line S(x) is below the curve of f(x), and the tangent line T(x) is above the curve of f(x).
Here's an example:

The first thing you should know is that this is an equation of the form:
y (t) = Asen (wt)
Where,
w: angular speed
By definition,
w = 2 * pi * f
Where,
f: frequency
Substituting values:
3520 * pi = 2 * pi * f
Clearing f:
f = (3520 * pi) / (2 * pi)
f = 1760 hz
Answer:
f = 1760 hz
