Question

Quadratic equations can be solved by graphing.
always
sometimes? which one?

Answer 1

yes,, the graph is a parabola, value of x at y = 0 gives the solution

Answer 2

I would really like to know how you can solve \(x^2+2=0\) using a graph. :)

Answer 3

sometimes would be the right one, because, sometimes, the parabola might not reach the x-axis so it might no have any one solution

Answer 4

so always?

Answer 5

oh gotcha thanks!
