how to find vertex in standard form Use the formula b 2a for the x coordinate and then plug it in to find the y A quadratic equation is written as ax 2 bx c in its standard form And the vertex can be found by using the formula b 2a For example let s suppose our problem is to find out vertex x y of the quadratic equation x 2 2x 3 1 Assess your a b and c values In this example a 1 b 2 and
A quadratic function can be written in vertex form as f x a x h 2 k where h k is the vertex and a is a constant multiplier In our example the vertex h k is 3 4 so we can write f x a x 3 2 4 Given that this passes through the point 1 2 we must have 2 a 1 3 2 4 4a 4 Subtract 4 from both ends to get To find the vertex in a standard quadratic equation we have to do two things 1 Find the x value of the vertex using the formula x b 2a x 4 4 x 1 2 Find the y value of the vertex by plugging in our value for x back into the original equation y 2 1 2 4 1 y 2 1 4

Standard form y 5 2 4 27 4 x 4 Vertex is at 4 5 Focus is at 43 4 5 directrix is y 11 7 y 2 10y 27x 133 0 or y 2 10y 25 25 27x 133 0 or y 5 2 27x 108 or y 5 2 27 x 4 or y 5 2 4 27 4 x 4 Comparing with standard equation y k 2 4 a x h h k being vertex we get here h 4 k 5 a 27 4 Vertex is at 4 5 Focus is at h a k or 4 How do you find the standard form of the equation of the parabola with Vertex at the origin focus at 0 4 How do you know if the conic section 3x 2 6x 5y 2 20y 13 0 is a parabola an ellipse a hyperbola or a circle
When both X 2 and Y 2 are on the same side of the equation and they have the same signs then the equation is that of an ellipse If the signs are different the equation is that of a hyperbola Example X 2 4 Y 2 9 1 9X 2 4Y 2 36 For both cases X The equation of the parabola is x 1 2 16 y 2 The vertex is a b 1 2 The directrix is y 2 The directrix is also y b p 2 Therefore 2 2 p 2 p 2 4 p 8 The focus is a b p 2 1 2 4 1 6 b p 2 6 p 2 6 2 4 p 8 The distance any point x y on the parabola is equidisdant from the directrix and the focus y 2 sqrt x 1 2 y 6 2 y 2 2 x 1 2 y
