Please help, what is the greatest common factor of
4ab²c⁴ - 2a²b³c² + 6a³b⁴c

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
