A player throws a football across the field. The equation h(t) = -16t^2 + 44t + 3.5 models the height, h (t) in feet of the football as a function of time, t in seconds.  a. Is this function linear, exponential, or a quadratic? How do you know?

b. What was the initial height of the football? What can you feature would represent there’s only graph of the function?

c. What is the maximum height of the football? What key feature would represent this on a graph of the function??

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
