My question is attached below. I think it's about derivatives and its calculus.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Which of the following would be a good name for the function that takes the weight of a box and returns the energy needed to lift it?

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.
