50 points!! h(x)=x^2 −1
What is the average rate of change of h over the interval -3≤x≤−1

iykvhchjgmh.Algal blooms have dramatic effects on water chemistry, most notably pH and dissolved oxygen (DO). When algae remove carbon dioxide during photosynthesis they raise the pH by increasing the level of hydroxide. The opposite reaction occurs during respiration when carbon dioxide is produced lowering hydroxide and lowering the pH.
