In class we learned about Quadratic Functions. Quadratic Functions is one of the important functions, noted as: y=ax^2+bx+c (with a,b,and c being real numbers and having a not equaling to zero.)
example:
1x5=5
2x4=8
3x3=9
4x2=8
5x1=5
We also learned about Vertex of a Quadratic Function, Axis of Symmetry of a Quadratic Function, and what Intercepts are.
A Vertex of a Quadratic Function is the coordinate where the turning point of the parabola is, which would be the highest or lowest point on the graph.
The Axis of Symmetry of a Quadratic Function is a vertical line that can run through the middle of the parabola.
There are 2 types of Intercepts that relate to a quadratic function. The x-intercept is the coordinate where the parabola passes through the x-axis, and the y-intercept is the coordinate where the parabola passes through the y-axis.
The maximum and minimum value is the highest/lowest number on the turning point of the parabola.
examples:
The vertex is: (0,-4)
The Axis of Symmetry is: x=-4
The x-intercept is: x=-2, x=2
The minimum is:-4
