Question

how do you write that on a graph?
y = − x2 + 3
y = x2 −3

fan and medal

Answer 1

\[y = − x^2 + 3 \\

y = x^2 −3 \]
two parabolas one open up one open down

Answer 2

what a nice picture

Answer 3

@satellite73 would they intersect?

Answer 4

yes, the one that opens down \(y=-x^2+3\) has vertex \((0,0)\) and the one that opens up \(y=x^2-3\) has vertex at \((0,-3)\)

Answer 5

Try to plot these points on the graph and you can check it..
