Please Help!! A Softball is thrown from a height of 20 feet at an initial velocity of 48 feet per second

1) Write the equation?
2) Find the height at t=3 second?
3) Find the vertex?
4) Find the axis of symmetry?
5) Find the time when it goes to the ground?
6) What is the maximum Height?
7) How long it takes to get to the maximum height?

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Zroms according to the synthetic division below, which of the following statements are true? check all that apply. 352 -2 6 -12 12 2 4 0 i a. (x-3) is a factor of 2x2 - 2x - 12. b. the number 3 is a root of f(x) = 2x2 - 2x - 12. c. (2x2 - 2x - 12) = (x + 3) = (2x + 4) d. (2x2 - 2x-12) - (x-3) = (2x + 4) e. (x+3) is a factor of 2x2 - 2x - 12. o f. the number -3 is a root of fx) = 2x2 - 2x - 12. previous

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
