Two questions: 

1) In your own words, define the word "rational" 
2) In your own words, define the word "roots"

This question relies on you knowing exactly what both of these things mean.

since you are a match teacher can you help me.

mathteacher1729 · Answer

Yes. I need to know whether or not you can define "rational" and "roots". :)

anonymous · Answer

i cant.. that's why i need help lol

mathteacher1729 · Answer

Gotcha. 
Ok. 

"rational" = a number that can be expressed as a fraction of two whole numbers

a / b 

7/23
-1/3

are both rationals. 

sqrt(2) is NOT a rational number.  There are no whole numbers a and b for which a / b = sqrt(2). 



"roots" = "where the parabola intersects the x axis".

okay, so know which graph is the right answer?
