All students: Not all curves are exponential

Many of you have picked up the bad habit of referring to all non linear curves as exponential. Exponential growth means the quantity goes as a constant to the t power i.e. K raised to the t power.

K to the t is very different from t to the k. In our constant acceleration labs displacement went as t squared or t to the 2, not as anything to the t power.

Curves that goes as t squared are parabolic not exponential.
