Answer:
Frequency is 3
Step-by-step explanation:
A sine function repeats in periods and it's frequency can be gotten using:
y(x) = sin(2πfx) where f is the frequency
We are given x = 4sin(6πx) + 1
This can be rewritten as: x = 4sin(3*2πx) + 1
Therefore, our f = 3.
Hence frequency of the sine function is 3.
