7. The sign of -10 tells you the signs of the roots are different, leaving only B and C as viable choices. It is easiest to evaluate the quadratic using the integer root. When we use -2, we find the equation is satisfied.

B is the appropriate selection.


8. The vertex form will be
.. y = a(x +1)² -10 . . . . . matching selections F and H
When we substitute x=1, we get 4a-10 = 2; a=3

H is the appropriate selection

Dis the correct answer
