2. ### For what values of the constant k will the following function NOT be its own inverse.?

Let (x - k ) / (x - 1) = y x - k = yx - y x = yx - y + k x - yx = y + k x(1 - y) = y + k x = (-y + k ) / (1 - y) x = (y - k ) / (y - 1) It would seem that the function is generally its own inverse...

5. ### From the formula, k (x)=2sin(x+pi)/(sin(x+pi)-3), what is k ^-1(x)?

k (x) = 2 sin (x+π) / (sin (x+π) - 3) = 2 (- sin x) / (- sin x - 3) = 2 sin x / (sin x + 3) = [2 (sin x + 3) - 6] / (sin x + 3) = 2 - 6 / (sin x + 3) So for k ^-1(x) we get x = 2 - 6 / (sin k ^-1(x) + 3) => 6 / (sin k ^-1(x) + 3) = 2 - x =>...
