the base, elevation (height) of the mountain changes at 3,000 m, and somewhere between 4 000 m and 7 000 m. The steepness of the first part of the climb occurs at a rate of change of 3, the second part a rate of change of 1, and the third part a rate of change of -2. At the end of the climb, she will have someone pick her up at a stop point at an elevation of 4 000 m. How would you approach solving this word problem?
