The equation for the area of a square could be written: A=s2
(4 points)
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?
1) This is a nonlinear function.
2) Some values in the table where s is the side length and A is the area could be:
s = 2, A = 4
s = 3, A = 9
s = 4, A = 16
s = 5, A = 25
3) The graph of the area of a square as a function of its side length is increasing. As the side length increases, the area also increases.
4) The domain of the function would include all positive real numbers, as the side length of a square can be any positive real number.
