Change a, Change the Graph Another form of the quadratic function is y = ax 2 c, where a≠ 0 In the parent function, y = x2, a = 1 (because the coefficient of x is 1) When the a is no longer 1, the parabola will open wider, open more narrow, or flip 180 degrees Examples of Quadratic Functions where a ≠ 1The standard equation of a parabola is (x−h)2 = 4p(y−k) ( x − h) 2 = 4 p ( y − k) where (h,k) ( h, k) is the vertex 4p 4 p is the length of the latus rectum Note that the squared willGraphing y = (x h)2 k In the graph of y = x2, the point (0, 0) is called the vertex The vertex is the minimum point in a parabola that opens upward In a parabola that opens downward, the vertex is the maximum point We can graph a parabola with a different vertex Observe the graph of y

It's a horizontal shift! The plot can be obtained by reflecting the function y=x^2/2 about the 45degree line All the previous answers (PSTricks, MetaPost, TikZ) use a plot to draw the parabola So they use a lot of segments to approximate it In the spirit of this answer I want to advocate to use a single quadratic (cubic) curve to draw the exact parabolaGraph x=y^2 x = −y2 x = y 2 Find the properties of the given parabola Tap for more steps Rewrite the equation in vertex form Tap for more steps Complete the square for − y 2 y 2 Tap for more steps Use the form a x 2 b x c a x 2 b x c, to find the values of a a, b b, and c c

The graph is a parabola If ( a , b ) is a point belonging to the parabola, that is 8 b = a 2 , then (− a , b ) also belongs to the parabola since b = (− a ) 2 Note that 6 • the line segment joining ( a , b ) and (− a , b ) is perpendicular to the y axis;Parabola The standard form equation of a general quadratic (polynomial functions of degree 2) function is f(x) = ax 2 bx c where a ≠ 0 If b = 0, the quadratic function has the form f(x) = ax 2 c Since f(x) = a(x) 2 c = ax 2 c = f(x), Such quadratic functions are even functions, which means that the yaxis is a line of symmetry of the graph of f
