Pick two of the statements below and provide a written explanation using complete sentences. a. choose one method that can be used to fix the y intercept of a quadratic function and explain how you can use that method to find the intercepts. b. choose one method that can be used to find the y intercept of a quadratic function and explain how you can use that method to find the intercepts. c. explain how to find the vertex and axis of symmetry of a quadratic function. d . explain how to find the maximum /minimum of a quadratic function.

Is the point (0, 8) on the x-axis or y-axis? how do you know?

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
