  2. 1. FALSE. pure imaginary numbers a+bi have a=0

    4. TRUE. a=bi is graphed as the point (a,b)

  3. False (is complex not imaginary)

    Yes I suppose although you can have a local minimum

    I guess you mean i^2, but that is just -1

    On the complex plane x and i y

  5. 1. true it is not a real number

    2 that is true, when graphing a function or a parabola, the minimum value is the smallest y value

    3 i^2 = -1, thus it is false

    4 complex numbers CANNOT be graphed on the coordinate plane (where would we put it?!) so false
