You can put this solution on YOUR website! Find the quadratic function y=ax2+bx+c whose graph passes through the given points.
(3,−11), (−2,−16), (1,−1)
-----
(3,-11) gives:: 9a + 3b + c = -11
(-2,-16) gives: 4a - 2b + c = -16
(1,-1) gives:: a + b + c = -1
--------
Use any method you know to solve the system for a,b,c.
-----------------
a = -2 ; b = 3; c = -2
-----
Equation:
y = -x^2 + 3x -2
