Determine the domain, codomain and range for the following functions. If the function is bijective state its inverse function a) f(x) = 2x ? 3 (x in R) b) f(x) = 2x?3 x+4 (x in R, x 6= ?4) c) f(x) = x2 + 1 (x in R ) If f(x) is not bijective, suggest a suitable restriction of the domain (and codomain) so that it will allow the definition of an inverse function.
