Answer:
I think is (x+0,5)^{2} - 6,25
Step-by-step explanation:
a(x-h)square + k
Answer: y = x² + x - 6
the equation is y = ax² + bx + c (a ≠ 0)
see in the graph, the equation passed through (-3;0), (2;0) and (0;-6), so we have:
9a - 3b + c = 0
4a + 2b + c = 0
c = -6
=> a = 1
b = 1
c = -6
=> the equation is y = x² + x - 6
