Question

Given the functions f(x) = 3x - 1 and g(x) = 3x + 4, which operation results in the smallest coefficient on the x term?

Addition
Subtraction
Multiplication
Two operations result in the same coefficient

Answer 1

Hii i dmed the girl gaby on twitter but she said she doesn't have a openstudy? So your lying

Answer 2

which one do you think it is?

Answer 3

@kyliejones which one did u pm ?

Answer 4

@kool_22 no idea

Answer 5

The one in your bio :)

Answer 6

Which one you think?

Answer 7

no u didnt lol cx

Answer 8

Yeah i did lol your a fake

Answer 9

ok whatever.. @Kyliejones ;p i just checked my messages and got nun so ...

Answer 10

Prove it.

Answer 11

Are you chatting here? Or here to get help with your question?

Answer 12

And I am water, so behave properly with me.. :P

Answer 13

And the two functions and tell me, what will be the coefficient of \(x\) after adding?

Answer 14

*Add.. very first word..

Answer 15

@eta tell her not me cx

Answer 16

and idk .-. @eta

Answer 17

You cannot add the two functions or have not learnt yet?

Answer 18

See, in adding, you just add the like terms of both functions:
\[f(x) + g(x) = 3x - 1 \color{red}{+} \; 3x + 4\]

Answer 19

So, what will you get when you add \(3x\) with \(3x\) ?

Answer 20

so 6x + 3

Answer 21

Good, here, what is the coefficient of \(x\)?

Answer 22

6

Answer 23

yep, remember it.
Now subtract them..

Answer 24

On subtracting, you will not have any \(x\) term, so this option is ruled out straightaway as you want to find smallest of coefficient of \(x\), and for that you definitely need \(x\)..

Answer 25

Now, comes Multiplication..
\[f(x) \cdot g(x) = (3x - 1)(3x + 4) = ??\]

Answer 26

9x + 12x - 3x + 3

Answer 27

Are you sure it is \(9x\)?

Answer 28

Should not it be \(9x^2\) ?

Answer 29

ummm ohhhh ok

Answer 30

What is the coefficient of \(x\) here?

Answer 31

9

Answer 32

Good, so with which one you got smaller?

Answer 33

addition

Answer 34

@ganeshie8

Answer 35

idk how to divide them..

Answer 36

Is there need to divide them?

Answer 37

No choices you have with Divide operation.
