The equation for the area of a square could be written: A = s^2.
1) Is this a linear or nonlinear function?
2) What are some values in the table where s is the side length and A is the area?
3) When you plot these points, is the graph increasing or decreasing?
4) What numbers would be included in the domain?
1) This is a nonlinear function.
2) Here are some values in the table:
s | A
------
1 | 1
2 | 4
3 | 9
4 | 16
5 | 25
3) The graph is increasing.
4) The domain would include all real numbers greater than or equal to 0, as negative side lengths are not defined for squares.
