The minimum value is the smallest y-value of a function. T RUE OR FALSE

i2 = square root of -1. TRUE OR FALSE

Complex numbers can be graphed on the xy coordinate plane. TRUE OR FALSE

**mathfailure**, Tuesday, November 20, 2012 at 12:01pm1. 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

**Damon**, Tuesday, November 20, 2012 at 12:04pmFalse (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

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