Question

I found the solutions ( think they are right) but I am having trouble finding the x intercepts.  The solutions I got are -sqrt(2), sqrt(2). The problem is 3x^2-6.

amistre64 · Answer

x intercepts occur when y=0

amistre64 · Answer

3x^2 -6 = 0

3x^2 = 6

x^2 = 2

so yeah, +- sqrt(2)

anonymous · Answer

so my solutions are also my x intercepts?

amistre64 · Answer

you really didnt provide something that was "solvable".  it was simply an expression

how did you get your "solutions"?

anonymous · Answer

I actually called a friend who tried to help me work thru it but they didn't understand it either.  Thats what we come up with. So I dunno.

amistre64 · Answer

the set of ordered pairs that would fit the expression draw a parabola on a graph

amistre64 · Answer

the places where that graph hits the y=0 (x ints) are then +- sqrt(2) when we solve for f(x) = 0

Ok i will try that...thank you.
