If f is a real valued funtion of a real variable defined by:
x^2 - 3x + 2
x-> ------------
x^2 +3x + 2
using the maximal domain convention. Determine whether f is injective and/or surjective and find its range. If f is not inective, demonstrate this by providing two different x-values x1 and x2 which satisfy f(x1) = f(x2) if f is not surjective demonstrate this by providing a value of y which is a member of the reals and for which no value of x satisfies f(x) = y
