Thanks for contributing an answer to Mathematics Stack Exchange!Y=x^24x2 Your questions can be answered after we change equation to standard form y=(xh)^2k, with (h,k) being the (x,y) coordinates of the vertex completing the square to convert to standard form, y=(x^24x4)24 y=(x2)^26 This parabola opens downward because the coefficient of x^2 is negative If the coefficient is positive, itPositive quadratic y = x^2 Negative quadratic y = x^2 Parabola (concave up) The vertex (p,q) is the minimum point when a parabola is concave up In this case y =q is the minimum value and so the range is R = {y e R y > q } Parabola (concave down) The vertex (p,q) is the maximum point for a parabola when it is concave down In this case y = q is the maximum value and so the range is R

In the theory of quadratic forms, the parabola is the graph of the quadratic form x 2 (or other scalings), while the elliptic paraboloid is the graph of the positivedefinite quadratic form x 2 y 2 (or scalings), and the hyperbolic paraboloid is the graph of the indefinite quadratic form x 2 − y 2 Generalizations to more variables yield further such objectsFind the arc length of the parabola {eq}y=x^2 {/eq} for {eq}0\leq x\leq1 {/eq} Parabola Parabola is symmetrical about the axis, it is a plane curve generally represented by U shaped parabola is 2 Rotating the parabola y = x2 by θ clockwise gives v = u2, where (u v) = (cosθ − sinθ sinθ cosθ)(x y) ie xsinθ ycosθ = (xcosθ − ysinθ)2 Putting θ = π 4 gives 1 √2(x y) = ( 1 √2(x − y))2√2(x y) = (x − y)2 which when expanded is x2

We're going to explore the equation of a parabola y=a x 2 b xc for different values of a, b, and c First, let's look at the graph of a basic parabola y=x 2 , where a =1, b =0, and c =0 Notice the graph opens up, the vertex is at x=0, and the yintercept is at y=0Let y = mx c be the tangent line to the parabola y = x^2 Solving these two equations together we get a quadratic equation in x that is x^2 mx c = 0 Since the line is a tangent line, the two values of x must be coincident, for that (b^24ac) = 0 or m^2 4c = 0 ==> c = m^2/4In this video we're going to talk about one of the most common types of curves you will see in mathematics and that is the parabola and the word parabola sounds quite fancy but we'll see it's describing something that is fairly straightforward now in terms of why it is called the parabola I've seen multiple explanations for it it comes from Greek para that root word similar to parable you

Exploring Parabolas by Kristina Dunbar, UGA Explorations of the graph y = 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 The given two curves are parabola y = x 2 and y 2 = x The point of intersection of these two parabolas is 0 (0, 0) and A (1, 1) as shown in the figure y 2 = x or y = √x – f (x)The simplest equation for a parabola is y = x 2 Turned on its side it becomes y 2 = x (or y = √x for just the top half)
