WebFind the Axis of Symmetry f(x)=4x^2+8x-3. Step 1. Write as an equation. Step 2. Rewrite the equation in vertex form. Tap for more steps... Step 2.1. Complete the square for . ... Since the value of is positive, the parabola opens up. Opens Up. Step 5. Find the vertex. Step 6. Find , the distance from the vertex to the focus. Tap for more steps... WebThe graph of a quadratic equation in the form y = ax2 + bx + c has as its axis of symmetry the line x = − b 2a . So, the equation of the axis of symmetry of the given parabola is x = − ( 5) 2 ( − 2) or x = 5 4 . Substitute x = 5 4 in the equation to find the y -coordinate of the vertex. y = − 2(5 4)2 + 5(5 4) − 1 = − 50 16 + 25 4 ... combustion of gas turbine WebGraphs of quadratic functions. All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a … WebThe equation of the line of symmetry. To describe a reflection on a grid, the equation of the mirror line is needed. Example. Reflect the shape in the line \(x = -1\).. The line \(x = -1\) is a ... dry gas seal in centrifugal compressor WebA line through a shape so that each side is a mirror image. When the shape is folded in half along the axis of symmetry, then the two halves match up. In this photo the white line … Weba line perpendicular to the axis of symmetry of a parabola; a line such that the ratio of the distance between the points on the conic and the focus to the distance to the directrix is constant. focus (of a parabola) a fixed point in the interior of a parabola that lies on the axis of symmetry. latus rectum. combustion of hydrocarbon word equation WebThe coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form. The coefficient of \(x^2\) is …
