Will Give Fan and Medal

Answer 1

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 + 44t + 12

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?

-0.25 < t < 2
0 < t < 3
1 < t < 2.4
1.4 < t < 3

Answer 3

I am between either 1<t<2.4 or 1.4<t<3

Answer 4

Answer 5

use the quadratic formula to solve -16t^2 + 44t + 12 = 0

or use a graphing calculator to find the roots of y = -16t^2 + 44t + 12

Answer 6

also keep in mind that t > 0 since negative time values make no sense

Answer 7

Okay One of the x values is 3

Answer 8

and the other one is -0.25

Answer 9

toss out t = -0.25

Answer 10

keep in mind that t = 0 is the lowest you can go

Answer 11

Okay

Answer 12

So would it be 1.4 < t < 3 @jim_thompson5910

Answer 13

you can go lower than t = 1.4

Answer 14

So it owuld be 0 < t < 3 ?
