Question

Algebra help? Will give medal!!!

Answer 1

1. The table below shows the values of y for each value of x.
X Y
-1 0
1 -1
2 1
2 -2

Part A: Does the table represent a function? Justify your answer by using the values shown in the table (4 points)
Part B: The function f(x) shown below represents the number of field goals Frank made at different distances, x, in meters, from the post.
F(x) = -x + 8
Calculate and interpret the meaning for f(5). (4 points)
Part C: Write an ordered pair to represent the input and output of the function in Part B when Frank is at a distance of p meters from the post. (2 points)
Part A:
Is the table a function? No
Justify your answer- use specific values in your answer.
-1 +1=0
1+1=2
2+2=4
2+2=4
Part B: Calculate f(5).
What does f(5) mean?
Part C: X represents meters from the post.
If we replace x with p, what is the y-coordinate? Write your ordered pair below:
(p, )



2. The table below represents a linear function f(x) and the equation represents a function g(x).
X F(x)
0 28

1 30
2 32

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Part A:
Find the Slope of f(x):
Find the Slope of g(x):
Write a sentence comparing the two slopes:
Part B:
What is the y-intercept of f(x):
What is the y-intercept of g(x):
Which one is greater?





3. The table below represents the displacement of a duck from its nest as a function of time.
Time (x) Displacement (y)
(hour) from nest ( Miles)
0 7
1 29
2 51
3 73
4 95

Part A: What is the y-intercept of the function and what does this tell you about the duck? (4 points)
Part B: Calculate the average rate of change of the function represented by the table between x=2 to x=4 hours? (4 points)
Part C: What would be the domain of the function if the duck continued to walk at this rate until it traveled 227 miles from the nest? ( 2 points)
Part A: What is the y-intercept?
What does this tell you about the duck?
Part B: What is the average rate of change from x = 2 to x = 4? Show your work.


Part C: Write a compound inequality of the domain if he traveled 227 miles from the nest?



4. Susan rented a flat at $200 per week. She also had to pay a deposit of $1400.

Part A: Write a function to show the total amount of money f(x) that Susan has to pay for renting the flat for x weeks. (4 points)

Part B: What is the total rent that Susan has to pay for using the flat for 12 weeks? (4 points)

Part C: If the deposit amount decreases by $100, what would be the total rent for 6 weeks? (2 points)

Part A:
F(x) =

Part B:
What is the total rent that Susan has to pay for using the flat for 12 weeks?
Plug and chug!

Part C:
If the deposit amount decreases by $100, what would be the total rent for 6 weeks?



5. Nicole rented a boat at $325 for 2 days. If she rents the same boat for 5 days, she has to pay a total rent of $892.
Part A:

Write the information above in point slope form:


Write this equation in slope intercept form:


Part B: Write the equation in part A in standard form (2 points)




Part C:

Describe the steps to graph the equation in Part A.

What is the label of the x-axis?

What is the label of the y-axis?

What is the slope?

What is the y- intercept?

What is the x-intercept?

Answer 2

oh god, is this a full test or what?

Answer 3

Lol I wish. My full tests are 30-40 questions

Answer 4

Just ask one at a time for the question you don't understand.

Answer 5

I think u should have did one question at a time

Answer 6

Yeah lol well for now can you help me in the first one?

Answer 7

Yea sure

Answer 8

1st its not a function because there are two x-values used in the table

Answer 9

ok

Answer 10

B. f(5) means u plug 5 for x and solve for y make sense?

Answer 11

yes!

Answer 12

so what did u get?

Answer 13

for what?

Answer 14

F(x) = -x + 8
f(5)= -(5)+8
f(5)=3 ?

Answer 15

ummmmm

Answer 16

u don't get it? ;/

Answer 17

kinda

Answer 18

k so what f(x) means function of x and we are given to find f(5) which means what y will be when we plug 5 for x...sorry for the confusion =0

Answer 19

gtg but thanks for the help, you got a medal

Answer 20

thanks ^.^ and anytime wish I could help u with more but the network is slow -.-
