Our function
f(t)= -16t^2 +100t
Independent and dependent variables
independent- time(t)
dependent- hight(h)
Domain and range
Domain- all real numbers
Range- Maximum
What is the height of the ball at 3.5 seconds? Is there another time at which the ball is the same hight? If so when
154, yes it is also the same hight at 2.75
Gloria and Earl
Glorias will hit the ground first. Her ball will go 100 feet at 2.5 seconds
Number 11
a:The slope, or the amount of distance the ball covers per second> effects the maximum and the roots
b: the function would be y=-16x^2 + 120x
c: Graph the new relationship between height and time. Make sure to label the graph and to graph the original function as well as the new function in the given graph.
d. What would be a reasonable domain and range of this new function?
Range-225
