Question

A quadratic function is a function of the form y=ax^2+bx+c where a, b, and c are constants. Given any 3 points in the plane, there is exactly one quadratic function whose graph contains these points. Find the quadratic function whose graph contains the points (0, -2), (-5, -17), and (3, -17). Enter the equation below. Function: y = 0

Answer 1

y=-x²-2x-2

Explanation:

Hey, just put x and y value to the statement and you will have 3 of them. Then solve the system :)

From 1st dot we see that c is -2, so a is -1 and b is -2. The result is:

y=-x²-2x-2
