A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear

ABecause the rate of change is constant the function is linear BBecause the rate of change is constant the function is nonlinear CBecause the rate of change is class=
