Suppose you have ax 2 bx c = y, and you are told to plug zero in for yThe corresponding xvalues are the xintercepts of the graph So solving ax 2 bx c = 0 for x means, among other things, that you are trying to find xinterceptsSince there were two solutions for x 2 3x – 4 = 0, there must then be two xintercepts on the graphGraphing, we get the curve belowY = ax 2 bx c In this exercise, we will be exploring parabolic graphs of the form y = ax 2 bx c, where a, b, and c are rational numbers In particular, we will examine what happens to the graph as we fix 2 of the values for a, b, or c, and vary the third We have split it up into three parts varying a only varying b only varying c onlyThe vertex form of a quadratic is given by y = a(x – h) 2 k, where (h, k) is the vertex The "a" in the vertex form is the same "a" as in y = ax 2 bx c (that is, both a's have exactly the same value) The sign on "a" tells you whether the quadratic opens up or opens down
Since y = mx b is an equation of degree one, the quadratic function, y = ax2 bx c represents the next level of algebraic complexity The parabola also appears in physics as the path described by a ball thrown at an angle to the horizontal (ignoring air resistance)The graph of the equation y = ax2 bx c is a parabola congruent to the graph of y = ax2 Recall that a quadratic function is any function f whose equation can be put in the form f(x) = ax2 bx c, where a ≠ 0 Thus, the graph of every quadratic function is a parabola, with y–intercept f(0) = cWhen a > 0 then from 4ay ≥ 4ac – b 2 we get, y ≥ 4ac – b 2 /4a Therefore, we clearly see that the expression y becomes minimum when a > 0 Thus, the minimum value of the expression is 4ac – b 2 /4a Now, substitute y = 4ac – b 2 /4a in equation ax 2 bx c – y = 0 we have, ax 2 bx c – (4ac – b 2 /4a) = 0 or, 4a 2 x 2 4abx b 2 = 0 or, (2ax b) 2 = 0
