The graph of a quadratic function is called a parabola. . If the coefficient of the squared term is positive, the parabola opens up. The general form of a quadratic function is --> y = ax 2 + bx + c. Since (0, -2) exists for the function, we can plug in those values:-2 = a(0) 2 + b(0) + c-2 = 0 + 0 + c-2 = c. So now our function so far is --> y = ax 2 + bx - 2. Changing a changes the width of the parabola and whether it opens up ([latex]a>0[/latex]) or down ([latex]a<0[/latex]). Fold the paper so that the two sides of the graph match up exactly. a. c.
