Question

Help me on this Please!!!

Answer 1

Function A. nonlinear

Function B. linear

Explanation:

Function A is nonlinear because the y values are changing at a nonlinear rate. To get from 0 to 1, the value is increased by 1. However, to get from 1 to 8, it increases by 7, which is different than before.

Function B is linear because the equation models a linear function. You can test this by drawing a table of values similar to Function A:

`\begin{center}\begin{tabular}{ c c c c } X & 1 & 2 & 3 \\ Y & 4 & 3 & 2 \\\end{tabular}\end{center}`

You can see the y values change at a linear rate of -1 constantly.
