Question 215703: Please help me solve AND graph the equation +y+=+-x%5E2+%2B+2x+%2B+3+
My instructor went over how to solve and graph the simpler equations, but this one is causing me a headache! I've tried to break down the problem, i.e. (x-1)(x+2), but nothing I plug in works! Thank you in advance!

You can put this solution on YOUR website!
y = -x^2 + 2x + 3 MY MISTAKE SORRY
y=-x^2+2x+3
y=(-x+3)(x+1)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-x%5E2+%2B2x+%2B3%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -x^2 +2x +3).
