do you know how to graph a quadratic equation?

anonymous · Answer

yeah barely...

anonymous · Answer

are you wanting to do this algebraicly or with a graph. that spelling is horrible sorry

anonymous · Answer

algebraically please

anonymous · Answer

$$(-\frac{ b }{ 2a },f(-\frac{ b }{ 2a })$$
this is to compute the vertex then from looking at the sign of the coefficient we know where the graph opens

anonymous · Answer

i have that part i have the x answer already i just don't know how to find y?????

anonymous · Answer

if you want to find this =to 0 you will either factor, complete the square, or use the quadratic formula

anonymous · Answer

look at the vertex formula. plug your -b/2a in as f(x)
