Part A.
Y intercept is the coordinate (0,y), when the function has an x value of 0, it is the y intercept.
In this case:
(0,5) =
y intercept = 5
IT tells about the turtle that it starts at a nest displacement of 5 miles.
Part B
The average rate of change represents the speed .
x1=1 ,y1=27
x2=4 ,y2=93
We have to calculate the slope if the function:

Replace:

Part C.
speed = distance /time
time= distance / speed
time= 225 / 22 = 10.22 hours
The domain will be
0< x ≤ 10.22
This is not right 1 is greater than 0
Answer:
a. 14
b. 7
Step-by-step explanation:
a. First we must add all the animals together,
Total Animals:
Birds: 6
Fish: 5
Mammals: 11
Reptiles: 3
Therefore our equation is:
6 + 5 + 11 +3 = 25.
Now, we must subtract by the number of mammals:
25 - 11 = 14
So our answer for a. is 14!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!
Mammals + Fish =
11 + 5 =
16
Next,
Birds + Reptiles =
6 + 3 =
9
Now, let us subtract them,
16 - 9 =
7
So our answer for b. is 7 more animals!
