These are 3 questions and 3 answers.1) Find
Answer: 4.Explanation:The expression means the
limit as the function f(x) approaches 2 from the right.Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.
That is the line that has the open circle around
y = 4, and that is the limit searched.
2) Use the graph to determine the limit if it exists.Answer: 

To determine each limit you
use the function from the side the value of x is being approached.Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.
3)
Answer: - 1
To find the limit when the function is approached to 3 from the left you
follow the line that ends with the open circle at (3, -1).Therefore, the limit is - 1.
We have that
h(t) = –16t²<span> + 14t
using a graph tool
see the attached figure
</span><span>the cricket’s hang time is the difference between point (0,0) and (0.875,0)
</span>(0.875-0)=0.875 sec
the answer is 0.875 sec
C. y= -28/x
y=k/x
cross multiply
k= y×x
k = -2×14
k = -28
y = -28/x [ equation connecting x and y]
