I need help /.\
A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:
f(t) = −16t^2 + 16t + 32
Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
0.5 < t < 1
0.5 < t < 2
1 < t < 2
1 < t < 1.5

Best ResponseYou've already chosen the best response.0highest point should be the vertex and the rightest zero x value of vertex = b/2a given ax^2 + bx + c so plug in and you will get your first point

Best ResponseYou've already chosen the best response.0the other point would be solve 16x^2 + 16x + 32 = 0 and take the positive answer, then you will get your other point

Best ResponseYou've already chosen the best response.0Thank you ^.^ A punter kicks a football upward with an initial speed of 48 feet per second. After how many seconds does the ball hit the ground? Use the formula h = rt − 16t2 where h represents height in feet and r represents the initial speed.

Best ResponseYou've already chosen the best response.0h = 0 when it hits the ground, therefore: 16t^2 + 48t = 0 _________________________ Factor out 16t 16t(t + 3) = 0 : Two solutions t = 0, when it begins it's upward journey and t = 3 sec, when it returns to earth
