graph{x^2 4x 2 10, 10, 5, 5} A you can see the quadratic equation has an ultra large U (INVERTED) So lemme show you what the table would look like so you could mark the co ordinates That should do it if you wanna exterd the graph further;(h,k) being vertex , here h = 2,k = 0,a = 1 Since a is positive, parabola opens upward Therefore vertex is at (h,k) or (2,0) Axis of symmetry is x = h or x = 2;Xintercept is found by putting y = 0 in the equation y = (x − 2)2 or (x − 2)2 = 0 or
Find the intercepts and the vertex Set x=0 to find the y intercept y = x^2 4x 1 y = 0^2 0x 1 y=1 Set y=0 to find the x intercept(s) if they exist y = x^2 4x 1 0 = x^2 4x 1 use the quadratic formula x = (bsqrt(b^2 4ac))/(2a) x = (4sqrt(4^2 4*1*1))/(2*1) x=2sqrt3 Now find the Axis of Symmetry (aos) aos = b/(2a) = (4)/(2*1) = 2 Find the vertexFree graphing calculator instantly graphs your math problems y 2 = x 2 4x Add (4/2) 2 , or 4, to both sides y 2 4 = x 2 4x 4 Now that the right hand side is a perfect square trinomial, factor it y 2 = (x 2)(x 2) y 2 = (x 2) 2 Subtract 2 from both sides y = (x 2) 2 2 When the equation is in this form, we can see that this is the graph of y = x 2 shifted to the right 2 units
If it's not what You are looking for, type in into the box below your own function and let us find the graph of it The graph of y^2=4x represents a graph of a quadratic function On the given graph you can find all of the important points for function y^2=4x (if they exist)Given a parabola whose equation is {eq}y=x^24x3 {/eq} Then we have that {eq}a=1, b=4, c=3 {/eq} To graph the parabola we first have to find its characteristic pointsY=x^24x4 (graph 300x0 pixels, x from 6 to 5, y from 10 to 10, x^2 4x 4) Intercepts(0,4)(2,0) Proof using the (2,0) x & y values
