Question

f(x) = cos(x - 4) - 8
How do you do this? please explain with answer.

Answer 1

How do you do what? Write instructions given.

Answer 2

find the inverse function of the function f

Answer 3

Solve for x
y-8=cos x - cos 4
cox x = y - 8 + cos 4
\[x =\cos^{-1} (y-8+\cos 4)\]

Answer 4

x=cos(y-4) -8
cos(y-4) = (x+8)
y-4 = cos^-1 ( x+8)
y= 4 + cos^-1 (x+8)

Answer 5

\[f^{-1}(x) = 4 + \cos^{-1} (x+8)\]

Answer 6

^ thats correct
