Which equation has this graph?
(see attachment)
y = x2  6x + 5
y = x2  6x + 5
y = x2  6x  5
y = x2 + 6x  5

Best ResponseYou've already chosen the best response.1If an equation has degree 2 (Meaning the highest exponent for x is 2) and the coefficient for x^2 is negative, then the parabola opens down. This rules out option B and C. Those would both be downward opening parabolas (Sad face) Now, just pick a point on the graph and see if it satisfies the remaining two equations. I like the point (0,5) because it's easy to calculate. Check: (0)^2 6(0) + 5 = 5? (0)^2 +6(0)  5 = 5?
