I'll try and keep a running list of corrections to the exam reviews!
9b. shrink of ½ (or 1/4?)
12b. constant (-inf, -2); inc (-2, 2); constant (2, inf)
13. min (1.38, .58)
18. 2x + 7
35. should be +15x instead of -5x
45. change 4loga7 to 4logay
50. I forgot to square and get rid of the square root! (duh) Should be (e^4.4 + 3)/2
