Quadratic Formula....Exponential Functions...yikes! Hi there, I am preparing to take the GACE for Middle Grades Mathematics, and while studying I have come across some material that is difficult and am wondering at what grade level it is covered. It seems advanced. The topic is the Quadratic Formula, more specifically narrowing into the discriminant and what kinds of roots come out of if the discriminant is negative, zero, positive, etc...It even discusses "i". Furthermore it discusses exponential functions of base "a", and that they take the form f(x)=a^x, where a>0 and not equal to 1. Wow. This is all out of a study guide for teacher certification, but even I can't figure some of this stuff out! Can anyone with experience teaching at the middle school level advise me as to whether or not this is expected of kids to learn at the middle school level? I am assuming this is considered Algebra, and I remember taking Algebra in high school before I took Trig. Thanks!!
