Best ResponseYou've already chosen the best response.1a) Write an equation in function notation to represent the height of the ball as a function of time b) State the degree of this function and whether the function is linear or quadratic. c) Use difference tables to confirm your answer in part (b) d) Graph the function where {tER  t > 0} e) At what time(s) is the ball at its greatest height? Express the height of the ball at this time in function notation f) At what time (s) is the ball on the ground? Express the height of the ball att this time in function notation

Best ResponseYou've already chosen the best response.2So thats good that means we would have to pick any real number greater than 0, make a table and graph our data

Best ResponseYou've already chosen the best response.1@diamondboy all of the 2nd differences are constant. they add up to 9.8. That makes it quadratic

Best ResponseYou've already chosen the best response.1so its at its highest point at 3 seconds or f(3)= 29.4 (3)  4.9 (3)^2 in function notation ?

Best ResponseYou've already chosen the best response.2hmmm...the reason I asked is I wanted to use the first derivative to find the maximum height

shelby1290

Best ResponseYou've already chosen the best response.1and the ball is at the ground at 0 f(0) = 29.4 (0) 4.9(0)^2

Best ResponseYou've already chosen the best response.1Oh i don't remember learning about first derivatives

diamondboy

Best ResponseYou've already chosen the best response.2but from the graph the highest point is at 3 seconds...and remember u are not using "f" you are using h

diamondboy

Best ResponseYou've already chosen the best response.2well yes you could do the last one like that or equate d equation to 0

shelby1290

Best ResponseYou've already chosen the best response.1alright so... h(3)= 29.4 (3)  4.9 (3)^2

shelby1290
