Do you wanna know if your function is quadratic?
If you got a table you don't even need a graph
Step 1 make sure the x values are increasing by a constant
and if not- stop right there!

Identifying a quadratic is easy as 1, 2, 3!
Easy as 1, 2, 3
1, 2, 3

Step 2 is to check your first differences
These are the differences between subsequent ys
If they're equal to each other, you know you're function's linear
If not continue on!

Identifying a quadratic is easy as 1, 2, 3!
Easy as 1, 2, 3
1, 2, 3

Step 3 is to check your second differences
These are the differences between the firsts you already found
If they're equal you've got a quadratic but if not,
you have a different type of nonlinear!
