Comparing parabolas
This image shows a standard parabola in blue.
and my parabola in red.
Identifying parts of a parabola
This is the base equation of a parabola. The different parts make the parabola look different.
The “a” part of the equation effects the change in height as in how skinny/fat the parabola is. It also effects the direction it opens in, “+” it opens up (-) it opens down.
The “h” in the equation represents the distance that the vertex is from 0 on the x-axis (remember that negative goes right and positive goes left)
The “k” is the same as the “h” but for the y-axis
This is my parabola explained
Blue is the “h” value (-6)
Green is the “k” value (+1)
Red is the “a” value (-2)
The green and blue arrows show how far the vertex is from (0,0)
Self assessment
- I made a graph of my equation and breakdown the equation in multiple ways.
- In my explanation I used lots of mathematical vocabulary to bring my point across
- I used lots of formatting by putting my information and graphs in the same place and lining them up well.
