Question

y=x^2-7

graph
find vortex

Answer 1

vortex, hmmmmmm I don't believe we have vortex in quadratics

Answer 2

I would find the x and y intercepts first to be able to graph them. for the x intercept plug 0 for y (0=x^2-7) and solve for x. For the y intercept plug 0 for x (y=7).

Answer 3

vertex

Answer 4

for the vertex use this formula: -b/2a

Answer 5

can you walk me through it ?

Answer 6

sure, gimme a sec to do it and then I'll show you

Answer 7

thanks

Answer 8

oh wait! its way more simple than having to use a formula! what's the vertex of every x^2 graph??

Answer 9

hmm 0
