Question: AVERAGE WEIGHT OF AN INFANT The following graph shows the weight measurements of the average infant from the time of birth (t = 0) through age 2 (t = 24). By computing the slopes of the respective tangent lines, estimate the rate of change of the average infant's weight when t = 3 and when t = 18. What is the average rate of change in the average infant's weight over the first year of life?
