Question

The vertex of a parabola is (-1.5, -12.5), and its y-intercept is (0, -8).
The x-intercepts of the parabola are_____ and _____

alekos · Answer

start by writing down the vertex form of a parabola

y= a(x-h)^2 +k

where h and k is the vertex (h.k)

ok what else?

alekos · Answer

substitute your values for the vertex and solve "a" using the y intercept

alekos · Answer

once you have the full equation you can then find the x intercepts if any

atomicreaper · Answer

Can you draw it or something, i am lost

atomicreaper · Answer

@alekos

alekos · Answer

no need to draw anything, just use algebra

atomicreaper · Answer

I am terrible at this. That is why im on open study

alekos · Answer

firstly substitute your  vertex values of h & k into the eqution
