Question I do not know how to graph the parabola y= x^2 Found 2 solutions by stanbon, jim_thompson5910 Answer by stanbon(757) (Show Source) You can put this solution on YOUR website! 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 parabola For a quadratic of the form x = ay2 by c, the axis is a line that passes through the vertex and is parallel to the y axis For our parabola, the axis is the line #y = 2 It's not part of the parabola itself, but lightly marking this line on your graph can help you see how the parabola curves symmetrically Step 5
The graph of a quadratic function is a Ushaped curve called a parabolaOne important feature of the graph is that it has an extreme point, called the vertexIf the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function If the parabola opens down, the vertex represents the highest point on the graph, or the maximumThe "general" form of a parabola's equation is the one you're used to, y = ax 2 bx c — unless the quadratic is "sideways", in which case the equation will look something like x = ay 2 by c The important difference in the two equations is in which variable is squared for regular (vertical) parabolas, the x part is squared; The beginning of an indepth study of graphing quadratic equations (parabolas) Includes the vocab words vertex and axis of symmetry
The Graph of a Quadratic Equation We know that any linear equation with two variables can be written in the form y = mx b and that its graph is a line In this section, we will see that any quadratic equation of the form y = ax2 bx c has a curved graph called a parabolaArrange the equation in the vertex form, Y = a(X h)^2 k or general form Y=aX^2bXc The equation is already written in general form Find the vertex by formula for X coordinate X = b/2a and then plugging the value of X in the equatioThe graph of mathy^2=ax/math will be parabola Two graphs are shown below for positive and negative values of matha=1/math matha=1/math matha=1/math

So the parabola has its vertex to the left on the y axis at (0,2) and its axis is a horizontal line parallel to the x axis with formula y = 2 It is symmetric about this axis The means that for every point (x,y) that lies on the parabola, so does the point (x,(4 − y)) The lower 'arm' of the parabola will intersect the x axis when y = 0Take several values for and find , make a table xy 00 13/2 Once you know the axis of symmetry, you can plug that value in for x to get the y coordinate These two coordinates will give you the vertex of the parabola In this case, you would plug 0 in to 2x 2 1 to get the y coordinate y = 2 x 0 2 1 = 0 1 = 1 The vertex is (0,1), and the parabola crosses the yaxis at 1
