Question

determine whether the formula determines y as a function of x if not explain why. 2) x=2y^2

Answer 1

y^2 = x/2
y = +sqrt (x/2) or - sqrt (x/2)
this is not a function because there are two possible outputs
so the formula does not determine y as function of x

Answer 2

what does it mean when they say to determine y as a function of x?

Answer 3

well find y in terms of x as i have done
and check if y is a function of x

a one-to-many relation like y = sqrt(x/2) is not a function

Answer 4

ohh alright i get it now thank you sooooooo much!!!! =]
