PLEASE HURRY write the equation of the inverse function y=1/2cos^-1(pix)-3

GaryK [48]

Answer:

$f^{-1}(x) = \frac{cos(2x+6)}{\pi }$

Step-by-step explanation:

$y = \frac{1}{2} cos^{-1} (\pi x)-3$

Firstly, we've to interchange the variables.

$x = \frac{1}{2} cos^{-1}(\pi y)-3$

Solving for y

$x = \frac{cos^{-1} \pi y}{2} -3$

Adding 3 to both sides

$x+3 = \frac{cos^{-1}(\pi y)}{2}$

Multiplying 2 to both sides

$2(x+3) = cos^{-1} (\pi y)\\2x+6 = cos^{-1} (\pi y)$

Taking cosine on both sides

$\pi y = cos (2x+6)$

Dividing both sides by y

$y = \frac{cos(2x+6)}{\pi }$

Replace y by $f^{-1}(x)$

=> $f^{-1}(x) = \frac{cos(2x+6)}{\pi }$
