Identifying Functions

Instructions:  Complete each scenario based on your favorite sport.  You may submit your assignment on paper or through Google Classroom.

Choose Problem 1a or Problem 1b

Problem 1a)  Shoot the basketball in a semicircle around the 3 point line in five locations for one minute.  Write five ordered pairs of the amount of shots made to the total shots. Does your shooting record represent a function?

Problem 1b)  Hit the softball in a semicircle around the 3 point line in five locations for one minute.  Write five ordered pairs of the hits made to the total throws. Does your hitting record represent a function?
