## Grade 11 Linear Equations CCSS: HSF-LE.A.1, HSF-LE.A.1a

Given the table below, which lists some of the values of the function $f(x)$, which of the following is true, and why?

 $\ \ \ \ \ \ \ \ \ \ \ mathbf{x} \ \ \ \ \ \ \ \ \ \ \$ $\ \ \ \ \ \ \ \ \ \ \mathbf{f(x)} \ \ \ \ \ \ \ \ \ \$ $0$ $-4$ $2$ $2$ $4$ $8$ $6$ $14$ $8$ $20$
1. $f(x)$ is linear, because the difference of y-values over equal intervals is constant.
2. $f(x)$ is linear, because the difference of x-values is constantly 2 units.
3. $f(x)$ is exponential, because the ratio of y-values over equal intervals is constant.
4. It cannot be determined whether $f(x)$ is linear or exponential, because there are no intervals of only one unit in the table.
