The general form of an equation of a parabola is y=ax^2+bx+c where (x, y) is a point on the parabola. if three points in a parabola are (2,-10), (-5,-101), and (6,-90), determine the values of a, b, and c, and write the general form of the equation.

Iwould say 48 bc the line of x is the line of 6 so 6×6=48

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
