1. ### Determine the value of k so that the function f(x)=(x-6)/(2x+k) will be its own inverse?

y = (x - 6) / (2x + k) x = (y - 6) / (2y + k) x * (2y + k) = y - 6 2xy + xk = y - 6 xk + 6 = y - 2xy xk + 6 = y * (1 - 2x) (xk + 6) / (1 - 2x) = y (xk + 6) / (1 - 2x) = (x - 6) / (2x + k) (xk + 6) * (2x + k) = (x - 6) * (1 - 2x) 2kx^2 + 12x + k^2 * x + 6k = x - 2x^2 - 6 + 12x...
