The graph models the function y = −x2 − x + 6. which attribute(s) of the graph tell you the root(s) of the function? determine the root(s).

In a graph the roots of the function are given by the cut points with the x axis.
 On the other hand, we have the following equation:
 y = -x2 - x + 6
 To find the roots, we equate to zero:
 -x2 - x + 6 = 0
 Rewriting we have:
 x2 + x - 6 = 0
 (x-2) (x + 3) = 0
 The roots are:
 x1 = 2
 x2 = -3
 
 The roots are:
 x1 = 2
 x2 = -3

Ithink the answer is c just trying to others
