Answer: 4 seconds
Step-by-step explanation:
Given: The function can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
Put h'(t)=0
Also,
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
Answer:

Step-by-step explanation:
means the y-coordinate of the point
that lies on
.
Aha! Now we have a path to the solution!
We can test random values for , such as
,
, or even
.
This leads us to drawing lines.
Answer: We draw the line (equivalent of testing out random points), and where it intersects the graph of
! is our answer!
(Note: it can only intersect once, otherwise it would fail the vertical line test and wouldn't be a function)
