Question

i have question plz help

Answer 1

@mhchen

Answer 2

Best results are obtained by presenting your question and showing your best work.

Answer 3

@tkhunny do you know anything about stocks?

Answer 4

You are told that it is linear.
You have the y-intercept. f(0)
You can calculate the slope with any pair of values.

Answer 5

@tkhunny if you are going to help then you need to give ever single valuable detail because my teacher is very sensitive to non shown work!

Answer 6

@tkhunny and shouldnt i put 30 in begcuase it represents f(x)

Answer 7

help
verb
1. make it easier for (someone) to do something by offering one's services or resources.

You are describing "Do it for me," I think.

Answer 8

"30" does not represent f(x). 30 = f(0). f(x) is to be determined.

Answer 9

@tkhunny NO not my intention!!!! Im just saying if we are going to work together make sure i included all the details so i dont get F lol

Answer 10

Follow the three steps I gave you. You will be completely covered.

Answer 11

What does the equation look like if you KNOW it is linear?

Answer 12

@tkhunny i got -25

Answer 13

@tkhunny thanks you!!!

Answer 14

it's destined to be a straight line i think

Answer 15

You are not answering my questions. "I go t -25" doesn't mean anything. For what? What question are you answering? Try to speak in sentences.

It is linear means: f(x) = mx + b - In the slope intercept form. It is not a destiny, it is a requirement. Al we have to do is find "b" and "m".

Answer 16

g(0)=8(0)-25

Answer 17

g(0)=0-25
=-25

Answer 18

Why are you doing anything with g(x). You need to find f(x).

Answer 19

well that is f(x) just didnt varible

Answer 20

f(x) = mx + b

You must find m and b.

g(x) is given as a formula.
f(x) is given as a table.

Answer 21

it gives equation....

Answer 22

You must be reading something that you are not posting.

g(x) is given as a formula or equation.
f(x) is given as a table.

Answer 23

OOOOOOOOOO i see sorry lol

Answer 24

What are the Slope and the y-intercept of f(x)? You must find them.

Answer 25

okay hold on

Answer 26

f(30)=0(30)- b right ?

Answer 27

You are given only f(0), f(1), and f(2). Where did you get f(30)? You need f(0) to find the y-intercept.

Answer 28

f(x) = mx+b

What is f(0)? f(0) = m(0) + b = b
We are also told that f(0) = 30.
Therefore, b = 30 and we have the y-intercept.

Answer 29

i see

Answer 30

You find the slope.

Answer 31

Slope = Rise / Run = Change in f(x) / Change in x = (y1 - y2)/(x1 - x2)

Answer 32

what are the points?

Answer 33

You are given three, (0,f(0)), (1,f(1)), and (2,f(2)). Just pick two.

Answer 34

so 0,0 and 1,1

Answer 35

What is f(0)? We already played with this one when we found the y-intercept.
What is f(1)?

Answer 36

Look at the table for f(x). What is f(0)?

Answer 37

30

Answer 38

Perfect. We have the first point. (0,30).
Find another point, using x = 1.

Answer 39

oh so for f(1) = (1,32)

Answer 40

Yes. Also, f(2) = 34, but we need only two.

Using (0,30) and (1,32), what is the slope?

Answer 41

2

Answer 42

Done. Now, can we answer the two questions?

Answer 43

for whats the formula

Answer 44

f(x)= 2(0)+30

Answer 45

We have for f(x)
1) The y-intercept is (0,30)
2) The slope is 2

If you would like to write it, feel free to do so. f(x) = 2x + 30, but we did nto need to do that to answer the two questions.

Answer 46

f(x) is NOT 2(0) + 30. That is f(0).
f(x) = 2x + 30

Answer 47

okay

Answer 48

There you go. Answer parts A and B.

Answer 49

I found the slope of f(x) by using the slope formula to calculate it, giving me the answer 2.

Answer 50

I found the slope of g(x) by using the point-slope form, giving 8.

Answer 51

Rock and roll! Keep it coming.

Answer 52

Comparing 8 for g(x) and 2 for f(x), you can see that the slope of g(x) is much greater than the slope of f(x).

Answer 53

you can go help others im going to write this down on my piece of paper

Answer 54

It's what I do. No need to ask.

Answer 55

lol i got a cramp in my fingers from writing so much... i barley write i mainly just type lol @tkhunny

Answer 56

@tkhunny thanks so much!!

Answer 57

No worries. Write good sentences for part B. That's what "Justify your answer" means.
