Write the equation for the inverse of the function.

y = cos 2x

The equation for the inverse of the function y = cos 2x. Thus, Option D is correct.

The inverse of a function f(y) refers to a property in which for every value of y in Y, there must be one x in (X) in a way that f(x) = y.

The inverse of a function reverses the effect of the original function.

Given that:

2y = cos⁻¹ x   provided that (y ∈ ║ -1, +1 ║)

∴

Therefore, we can conclude that the inverse of y = cos 2x is . Option D is correct.

Step-by-step explanation:

y = Cos(2x)

Inverses for trig functions are found the same way as any other inverse. The trick is to interchange x and y.

x = cos(2y)             Take the inverse cos of both sides.

cos-1(x) = 2y           Divide by 2

1/2 cos-1(x) = y
