y^2=3x

My answer:

3x=y^2|0|3|12|27

y |0|1| 2| 3

y^2=3x is a function because the coordinates I chose are not duplicated.

**Damon**, Friday, March 28, 2008 at 6:07pmy^2 = 3 x

y = + sqrt(3x)

BUT

y = - sqrt (3x)

for example if x = 12

y = sqrt(36) = 6

BUT

y = -sqrt(36) = -6

works

so there are two values of y for every x

NOT a function
