Whats going on?
2.) What is our independent variable
What is our dependent variable?
3.) Our domain and range!
R: 0 ≤ y ≤ 157
4.) HOW LONG IS the golf ball in the air?
5.) What is the maximum height of the ball?
(graphs title: height in feet of golf ball vs. time in seconds)
6.) How long after it is hit does the golf ball reach the maximum height?
10.) Suppose Gloria and Earl stand side by side and teed off at the same time.
11.) Suppose that Earl hit a second ball from a tee that was elevated 20 feet above the fairway.
a.) What effect would the change in elevation have on the graph?
-There is now a c in the function which means that there is now a y-intercept of 20. The ball that was teed off 20ft above the fairway will reach a greater height (it will be higher) than the original ball. Therefore, the y-intercept would be 20 feet higher, meaning it would intercept the y-axis at (0,20). The time it takes to reach the vertex will be the same, but the vertex will move up 20 units.
Reasonable domain and range
domain: 0 ≤ x ≤ 3.13
range: 20 ≤ y ≤ 176.25
