What function is not symmetrical and does not have a constant rate of change

Question

linear, quadratic, exponential

Answer 1

The exponential function does not exhibit symmetry nor does it have a constant rate of change ( i.e. slope) since the curve either grows faster and faster as the "x" value increases ( for a growth situation) or the curve will decline slower and slower as the "x" value increases ( for a decay/decline situation).
