A polynomial function of degree two is called a quadratic function. The graph of a quadratic function is a parabola. A parabola is a U-shaped curve that can open either up or down. The axis of symmetry is the vertical line passing through the vertex. Quadratic functions are often written ...
(Figure) represents the graph of the quadratic function written in general form asy=x2+4x+3.y=x2+4x+3.In this form,a=1,b=4,a=1,b=4,andc=3.c=3.Becausea>0,a>0,the parabola opens upward. The axis of symmetry isx=−42(1)=−2.x=−42(1)=−2.This also makes sense...

Axis of symmetryThe quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0. Solving the equation gives the two points where the parabola crosses the x-axis (the two values of x when y = 0):What ...
The vertex of a quadratic function (which is in U shape) is where the function has a maximum value or a minimum value. The axis of symmetry of the quadratic function intersects the function (parabola) at the vertex.Quadratic Functions Formula...
The formula to calculate the axis of symmetry is: x=−b2ax=2a−b Thus, the x coordinate of the axis of symmetry is equal to negative b divided by 2 times a. Frequently Asked Questions Why is the quadratic formula important? The quadratic formula is important because it allows us ...
