In week 7 we started looking over properties of a quadratic function. In this lesson we determined the characteristics of a quadratic function and how to solve it.

We determined if a table of values represented a quadratic function. You could tell this by seeing how much y went up.

Example: 5,0,-7,-16,-27

to get from 5-0 you -5, to get from 0–7 you -7, and to get from -7–16 you -9. The pattern here is you are adding 2 to how much you subtract each time

A few of the first things I learned include; finding the vertex, the x and y intercepts, the line of symmetry, and the domain and range.

Example:

Vertex: (-2,2)

x-intercepts: (-3,-1)

y-intercept: (6)

Line of symmetry (-2)

Domain: (XER)

Range: (y>-2)
