Question

what is the general equation of cosine function with a amplitude of 3 a period of 4pi and a horizontal shift of - pi

Answer 1

The answer is C

Explanation:

I just took the test

Answer 2

The general form of such an equation will be

`f(x)=A\cos\left((2\pi(x-B))/(C) \right)+D`
where
A = amplitude (3)
B = horizontal shift to the right (-π)
C = period (4π)
D = vertical offset (0)

Your equation will be ...

`f(x)=3\cos\left((x+\pi)/(2)\right)`
