1. f(x) = x^2 - 6x + 13, x is not less than 3
Obtain the inverse function, stating its domain and range.
2. g(x) = exp(-2x), obtain its inverse function.
3. f(x) = 1 + x^0.5 , x is not less than 0.
Solve the equation f(x) = f^-1 (x)
4. f(x) = (x-2)^2 + 1 ; x is not less than 2.
Sketch the graph of y = f(x) ; y = f^-1 (x) ; y = ff^-1 (x)
