Question Identify the vertex, axis of symmetry, and intercepts for. {eq}y= 2x^2 4x 8 = 0 {/eq} Parabolas The equation of a parabola is a quadratic equation whose points are all the same distance from a focus point and a directrix line. To find the vertex form of the parabola, we use the concept completing the square method Vertex form of a quadratic function y = a(x h) 2 k In order to find the maximum or minimum value of quadratic function, we have to convert the given quadratic equation in the above form.

The vertex of any quadratic of the form y=ax^2bxc is at x=b/2a That follows from the quadratic formula So in this case the vertex would be at x=8/2=4 Insert 4 into the quadratic and you'll get y==12 So the vertex is at (4,12).  The axis of symmetry and the vertex of this quadratic function are calculated by hand The results are compared with the results obtained by using a graphing.  To change the expression (x2 2x) into a perfect square trinomial add (half the x coefficient)² to each side of the expression Here x coefficient = 2 So, (half the x coefficient)2 = (2/2)2 = 1 Add and subtract 1 to the expression The vertex form of the parabola with vertex (h, k) and axis of symmetry x = h is y = a (x h)2 k.

Here h is the xcoordinate and k is the ycoordinate Vertex formula Vertex is calculated from two types of equations standard and vertex form For standard form (y = ax 2 bx c) h = 2b/a k = c b 2 /(4a) (Alternatively, you can convert standard form into vertex form to identify the values) For vertex form (y = a*(xh) 2 k) Simply. To find the vertex, we first need to find the axis of symmetry (ie the xcoordinate of the vertex) To find the axis of symmetry, use this formula From the equation we can see that a=1 and b=2 Plug in b=2 and a=1 Negate 2 to get 2 Multiply 2 and 1 to get 2 Reduce So the axis of symmetry is So the xcoordinate of the vertex is Lets plug this into the equation to find the ycoordinate of the.

0 = x 2 2x 8 (which factors) 0 = (x 4)(x 2) x = 4 or x = 2 So this parabola has two xintercepts (4,0) and (2,0) To find the yintercept we plug in 0 for x y = (0) 2 2(0) 8 = 8 So the yintercept of the parabola is (0,8) To find the vertex we use and to find k, we plug in 1 in for x k = (1) 2 2(1) 8 k = 1 2 8. Vertex form Vertex form is another form of a quadratic equation The standard form of a quadratic equation is ax 2 bx c The vertex form of a quadratic equation is a (x h) 2 k where a is a constant that tells us whether the parabola opens upwards or downwards, and (h, k) is the location of the vertex of the parabola.

 Again, 2f(x) would be 2x 2, not x 2 For y = x 2, the vertex is at (0, 0), so doubling the yvalue has no effect The graph of y = 2x 2 will also have (0, 0) as its vertex All other points will be twice as far away from the xaxis as those on the graph of y = x 2. So, if we write the function in the vertex form, it will be, y = 4(x (3)) 2 4, so h is, in fact, 3 In the second eqaution, y = 4x 2 24x 40, we would find the vertex (x, y), by first using the formula to get the xvalue, x = b/2a x = (24)/2(4) x = 24/8 x = 3 To find the yvalue of the vertex, substitute 3 in for x and solve for y.
