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.

- What is the difference between the input and the output of a function?arrow_forwardAn outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.arrow_forwardClassify the function as being even, odd, or neither.arrow_forward
- Graph f(x)=2x10. Picka set of5 ordered pairs using inputs x=2,1,5,6,9 and use linear regression to verify the function.arrow_forwardWhy does the vertical line test tell as whether the graph of a relation represents a function?arrow_forwardFill in the blanks. For an equation that represents y as a function of x , the set of all values taken on by the ________variable x is the domain, and the set of all values taken on by the ________ variable y is the range.arrow_forward
