This Table is Quadratic because it is first decreasing and then it is going down to 0 but then it increases back up to where it started to 6. You can tell if a table is quadratic because it is either increasing or decreasing first but then it stops at 0 in the middle and then it starts to increase or decrease again just opposite than the first time. Ex: This graph is first decreasing and then it stops at 0 in the middle then it starts to increase up to the number you started on because you do the opposite than the first time.
Graph

This is a Quadratic graph. It is a quadratic graph because it has a U shape. A quadratic graph can have a U shape like this one or it can have a n shape it depends on weather the graph is positive or negative. If you have a U shape your graph is going to be positive, if you have a n shape your graph is going to be negative.
Equation

This is a Quadratic equation. It makes a U shape because it is a positive equation, but if it had a negative number it could be a n shape. If you would make a table or a graph with this equation you would make a table or a graph that looks like the ones above.
Reflection
In this investigation I learned how to make a Quadratic table, graph, and equation. I learned that if I had an equation I could make a graph and a table with just an equation.
