Answer:

use the straight line test

Step-by-step explanation:

use your pencil or draw a line horizontally (like this -> I )anywhere on the graph. If it's a function, it will only touch the line at one point no matter where you put the line.

A WAY easier (and faster), way to know if it is a function is to see if there are two of the same x-intercept (which make a vertical line). If there is, then it is NOT a function.

A = amount

.01a + .05a + .1a = 1.28
Combine like terms.
.16a = 1.28

8 * 3 = 24
