The graph of y = ax^2 + bx + c is shown below. Find a times b times c. (The distance between the grid lines is one unit.)

We know c is -1 cus c is the one that determines the y intercept.

Plug in the coords of one of the dots adn subtract the two equations repeat till you get two equations with b and a u want to take away c cus we already know it.

2=3a+b

1=7a+b

4a=-1

a=-1/4

b=11/4

-1*-1/4*11/4=11/16
