Quadratic Functions are used to simulate real-life situations.
A quadratic function is an equation in the form:
y = ax2 + bx + c
I will be able to graph a quadratic function.
I will be able to find the equation of the axis of symmetry and the coordinates of the vertex.
of an object thrown in space is a parabola.
To graph a parabola we create a table of values and then plot the points. Lets Graph: y = x2 – 2x – 3Graphing A Parabola
y = x2 – 2x – 3
Lets Graph: y = -x2 + 2x + 1
Quadratic Equation: y = ax2 + bx + c

Lets look at the equation: y = -x2 + 4x – 1
a = -1 b = 4 c = -1

Lets look at the equation: y = x2 – 2x – 8
a = 1 b = -2 c = - 8
