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 $f^{-1}(x)$

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

Simplify the rational expression.

Vadim26 [7]

Answer:

$\frac{x-6}{x-9}$

Step-by-step explanation:

Given

$\frac{x^2-2x-24}{x^2-5x-36}$ ← factor the numerator and denominator

= $\frac{(x-6)(x+4)}{(x-9)(x+4)}$ ← cancel (x + 4 ) on numerator/ denominator

= $\frac{x-6}{x-9}$
