John runs at different speeds as part of his training program. the graph shows his target heart rate at different times during his workout. on which interval is the target heart rate strictly increasing then strictly decreasing

im guessing (23,14). hope this : )

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
