4) Suppose the insect population was 105 insects at the beginning of the period shown. Based on the rate of change function, make a rough sketch of two functions: a) the function that gives the net accumulation of the insect population at every number of months starting from x 0 months and b) the function that gives the total accumulation of the insect population starting from x = 0 months. 200 150 100+ 0.4 c) The exact rate of change function given was named rp. The sketches you made above were attempts to represent Ap (the exact net accumulation function) and P (the exact total accumulation function, or the population function). Explain what these functions have to do with the endeavor "You know how fast a quantity is changing at every moment, and you want to know how much of the quantity you have at every moment."
