Question

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 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

Answer 1

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

Answer 2

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

Answer 3

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

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

Answer 8

^ answers are wrong

Answer 9

yall realize that these questions are randomized and they're not always going to be the same right

Answer 10

It's not randomized bozo its a different test

Answer 11

Yall finna get slimed out over some math smh
