A scatter plot is depicted with a vertical y-axis and a horizontal x-axis, both unlabeled except for the notations 'y' and 'x' at their respective ends. There are seven distinct black dots scattered across the plot, with coordinates at $\left(1,\frac{11}{20}\right)$(1,1120), $\left(2,\frac{27}{20}\right)$(2,2720), $\left(3,\frac{53}{20}\right)$(3,5320), $\left(4,\frac{69}{20}\right)$(4,6920), $\left(5,\frac{17}{4}\right)$(5,174), $\left(6,\frac{101}{20}\right)$(6,10120), and $\left(7,\frac{107}{20}\right)$(7,10720). The dots form a not-so-perfect straight line if they are connected. The graph indicates that as time increases, the number of parks in a city also increases. The coordinates of the points are not explicitly shown in the image.

F-IF.4'''

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. '''Include rational, square root and cube root; emphasize selection of appropriate models.
