- is √-4 complex number? - is 3+4i non-real?
- is 1/pi non-real?

- True/False -
All imaginary numbers are complex

The sum of two non-real numbers is always non-real

If a decimal does not terminate it is always irrational

If a number is complex it must contain an imaginary component.

(Thank you so much)

What is the equation of the following graph in vertex form? parabolic function going down from the left through the point zero comma twelve and through the point two comma zero and turning at the point four comma negative four and going up through the point six comma zero and continuing towards infinity courtesy of texas instruments a: y = (x − 4)2 − 4 b: y = (x + 4)2 − 4 c: y = (x + 2)2 + 6 d: y = (x + 2)2 + 12

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
