Concept explainers
Homeruns A baseball analyst wishes to find a function that relates the distance, , of a homerun and the speed, , of the ball off the bat. Consider the data shown to the right.
(a) Does the relation defined by the set of orders pairs represent a function?
(b) Draw a
(c) Using a graphing utility, find the line of best fit that models the relation between the speed off the bat and the distance of the homerun?
(d) Interpret the slope.
(e) Express the relationship found in part (c), using function notation.
(f) What is the domain of the function?
(g) Predict the homerun distance if the speed of the ball off the bat is 103 miles per hour.
