Codes beginning with 0 or 1 should also be excluded. How many different area codes were possible under these old rules?

Thanks

equation: 4x - 2y^2 = 9

would the equation be:
y= +/- sqrt 4.5 + 2x

if it is, then "y" is not a function of "x" right?

thanks for your help.

we were given this problem by my maths teacher.basically just tell me what is wrong with this :
a=b+c
a(a-c)=(b+c)(a-c)
a2-ac=ab-bc+ac-c2
a2-ab-ac=ac-bc-c2
a(a-b-c)=c(a-b-c)
a=c



come on have a go !!!
