The differences between f(x) values are 3, 6, 9, 12. The differences between those are constant: 3. When "second differences" (for uniformly spaced x values) are constant, the function is quadratic.

_____

The degree of the function is equal to the level of differences that are constant. Linear (1st-degree) functions have 1st differences that are constant; cubic (3rd-degree) functions have 3rd differences that are constant.

If each level of differences increases in the same way, the function is exponential.

<h3>QUESTION A:</h3>

Graph B.

The information is presented most clearly here, being centered and climbing steadily which prevents the influence of bias in the presentation. As stated, his presentation is intended to be neutral.

<h3>QUESTION B:</h3>

Graph C.

This graph tricks the human brain into thinking that the increase is less prominent than we might perceive it in Graph A or B. This is because it is located lower and has a shallower slope. The campaign that wants to prevent immediate radical action (action which would harm the native species) would want to use this one as it might convince the city counsel that the issue is not urgent enough to take such actions so quickly.
