Algebra 2 help :)

Any number in the form of a+bi , where a and b are real numbers and b not equal 0 is considered a pure imaginary number. TRUE OR FALSE
The minimum value is the smallest yvalue 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

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 
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 
1. FALSE. pure imaginary numbers a+bi have a=0
4. TRUE. a=bi is graphed as the point (a,b)
