The graph of a quadratic equation in two variables (y = ax 2 bx c) is called a parabola Secondly, how do you find the Y intercept of ax 2 bx c? The extreme point of the quadratic function f(x) = y = ax 2 bx c is The symmetrical axis is x = 3 and the extreme value is 4 After obtaining the intersection of the X axis, the intersection of the Y axis, the extreme point, we can draw a graph of the quadratic function The graph of a quadratic function is a parabola The parabola can either be in "legs up" or "legs down" orientation We know that a quadratic equation will be in the form y = ax 2 bx c Our job is to find the values of a, b and c after first observing the graph

#color(blue)("Some observations")# The #x^2# is positive so the general graph shape is #uu# Consider the generalised form of #y=ax^2bxc# The #bx# part of the equation shifts the graph left or right You do not have any #bx# type of value in your equation So the graph is central about the yaxis The #c# part of the equation is of value 1 so it lifts the vertex upFor example, in the quadratic function we saw above, the standard form is y = (x 1) 24, so the vertex is at the point (1, 4) Justification for the connection between the formula in standard form and the vertex comes from the graphing techniques we studied earlier For the quadratic y = x 2, the vertex is the origin, (0, 0) Subtracting h from x means we have a right horizontal shift by hWhere a line crosses the yaxis of a graph Just find the value of y when x equals 0 Example In the above diagram the line crosses the y axis at y = 1 Example Here the line crosses the y axis at y = −2 Point The yintercept is an (x,y) point with x=0, so we show it like this (try dragging the points)
