A researcher in physiology has decided that a good mathematical model for the number of impulses fired after a nerve has been stimulated is given by y = -x² + 50x - 70, where y is the number of responses per millisecond and x is the number of milliseconds since the nerve was stimulated. a) When will the maximum firing rate be reached? b) What is the maximum firing rate?
