The graph of which quadratic equation is shown below?
y = x^2 + 2x − 8
y = x^2 − 2x − 8
y = −x^2 − 2x + 8
y = −x^2 − 4x − 8

Best ResponseYou've already chosen the best response.0ok, set everything I drew above to zero, that is like saying: When is Y zero? When Y is zero it touches the xaxis

Best ResponseYou've already chosen the best response.0So then the answer is y = −x^2 − 2x + 8 I factored out the negative sign above.
