Determine a quadratic function f(x) for the graph given below.

A ball is thrown upward from the roof of a building with an initial velocity of 16 ft/sec. The height of the building is 50 ft. The equation for the height of the ball after t seconds is given as s(t) = -16t2 + 16t + 50. Determine the time when the ball will achieve a maximum height. Also, find the maximum height.
In a certain university, the number of students who participated in the yearly fundraising activity from 2011 to 2018 can be modeled by A(x) = 3x2 - 52x + 255, where x = 1 represents the year 2011. From 2018 to 2022, the number of students is represented by A(x) = 42x - 305. Graph y = A(x) for the years 2011 to 2022 and determine the year in which the number of students who participated is the least.
Justify that the polynomial f(x) = x3 + 4x - 3 has a real zero in between 0 and 1 by using the Intermediate Value Theorem.
Determine if the following function is a polynomial or not. If it is, what is its degree?
f(x) = x1/5 - 5x6 + 1
Consider the function f(x) = -(x - 4)2 + 6 and find the largest open interval of the domain at which the function is increasing and decreasing.
