The equation for the area of a square could be written: A = s^2 (4 points)

Question

1) Is this a linear or nonlinear function?
2) What are some of the 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?

Answer 1

1) This is a nonlinear function.
2) Here are some values for the table:

s (side length) | A (area)
--------------------------
1 | 1
2 | 4
3 | 9
4 | 16

3) When you plot these points, the graph is increasing.
4) The domain for this function would include any positive real numbers for the side length.
