Question

Evaluate each of the functions below at x = 1, 2, 4, 8, and 16. Plot the graph of each function. Classify each as linear, quadratic, polynomial, exponential, or logarithmic, and explain the reasons for your classifications. Compare how quickly each function increases, based on the evaluations and graphs, and rank the functions from fastest to slowest growing.

Grading rubric for each equation A-E:
1. evaluation at x = 1, 2, 4, 8, and 16 2
2. graph function 3
3. classify and explain why for each function 2



A. f(x) = x3 - 6x2 - x + 2

B. f(x) = ex

C. f(x) = 4x - 1

Answer 1

Well this is a long question!!!

Answer 2

i dont understand what im suppppppppose to do? I tried idk if the anwers are right>>check?

Answer 3

First plug in all the x values into the first second and third equations. Then you will get the y values The x and y values are coordinates on the graph so u can graph it

Answer 4

Did u get what I said?

Answer 5

i think hold on k?

Answer 6

f(1) = (1)3 - 6(1)2 - (1) + 2

Answer 7

so y= -4
so the coordinates on the graph wld be (1,-4)

Answer 8

huh?

Answer 9

Its is 1 ^3 right?

Answer 10

and 2 yes

Answer 11

add the equation by yourself and tell me what u get

Answer 12

-5?

Answer 13

Stop being annoying!!!!

Answer 14

I am just teasing u

Answer 15

huh?
what i do?

Answer 16

No I am talking to sheg

Answer 17

-7+3=-4

Answer 18

where do you get that from?

Answer 19

1-6-1+2=-4

Answer 20

your confusing me horribly, am i finding the vertex?

Answer 21

Nope you r plugging -1 as the x value and the you solve it to get the y value

Answer 22

They want to know what the y value is at x=1 in all the three equations

Answer 23

Did u get that or totally not?

Answer 24

-4 right?

Answer 25

ya that is the right answer but do u understand what u did?

Answer 26

just not the graphing?

Answer 27

no vertical asymptoties horizontal=-4 no oblique

Answer 28

well once you get all the coordinates then it is easy to graph the first one and the second one

Answer 29

The first one is a cubic function the second one is an exponential function and the third one is a line but u wld see that if you wld graph all the points

Answer 30

so its (1,-4)

Answer 31

yes and this point is part of the first equation only

Answer 32

Now plug in the second x value into the first equation and then the third and the fourth and then u have enough points to graph the first equation

Answer 33

how do i do the ranking?

Answer 34

What is ranking?

Answer 35

d explain the reasons for your classifications. Compare how quickly each function increases, based on the evaluations and graphs, and rank the functions from fastest to slowest growing.

Answer 36

The fastest function is the second one and it is growing exponentialy. the second is the first equation and it is cubic and the third is the last equation which is linear and is growing by a slope of 4

Answer 37

I am guessing this is what they want. I have never done ranking b4. Th eorder it increases is definitely correct but the explanation may be incorrect

Answer 38

can u help me on b?
