Given f(x)=x^2−4x+5, answer the questions that follow. a. What type of function is this? b. Graph this function labeling at least 5 points. c. Find the domain and range of the function (use whatever notation you want). d. On the interval (−[infinity],[infinity]), is f one-to-one? If yes, prove it, if not, explain why. e. On the interval [2,[infinity]), is f one-to-one? If yes, prove it, if not, explain why.
