Question

Math help

Answer 1

I need an intro to sum, diff, prod, and quotient problems....show me how it’s done at intro level

Answer 2

Post it

Answer 3

The textbook starts from rational functions... but it’d be too steep of a learning curve for me to adapt to... gimme some basic questions to get me warmed up

Answer 4

Gimme 4 questions...one for each and after that i’ll post questions from my textbook

Answer 5

You probably already have those in your book

Answer 6

I don't post sample questions. I have to get that from you to know what you're working on.

Answer 7

My textbook doesn’t show me how to solve those questions...

Answer 8

Well, post a question from from book.

Answer 9

K wait, let me post an example from the textbook.

Answer 10

\[F(x) = \frac{ 1 }{ 3x-1 }\] and \[G(x) = \frac{ 2 }{ 4-x }\], find the sum, prod, diff, and quotient of f and g.

Answer 11

I didn’t want to start from fraction functions.tho

Answer 12

Don’t blame me if i struggle

Answer 13

You must mean to find \((F + G)(x)\), \((F - G)(x)\), \((F /G)(x)\) and \((F \cdot G)(x)\)

Answer 14

You'll be doing compositions as well

Answer 15

(fºg)(x)

Answer 16

So all you're doing is just adding/subtracting/multiplying/dividing fractions. Nothing you haven't already done before.

Answer 17

Let’s start with adding the funcs

Answer 18

I have to get back to my own work. @Ferredoxin4 can help you if he has time.

Answer 19

Thanks hero. Appreciated

Answer 20

I literally did this all by myself.. no cheating, no looking off the textbook

Answer 21

Wait, do i need to simplify that thing at the end any further??

Answer 22

If all of that is right, you should try factoring the denominator

Answer 23

Are you trying?

Answer 24

I was eating...gimme 5 minutes plz

Answer 25

b r u h

Answer 26

Back, let’s do this.. let me draw

Answer 27

Wait, is this just the sum of the functions??? Does that mean i have to do diff, sum, and quotient after this???

Answer 28

Let’s do the diff next... let me draw.

Answer 29

yes, that is just the sum

Answer 30

All that work for just sum?? /.-

Answer 31

Unfortuntely yes

Answer 32

You look like you know what you're doing. The only thing to worry about is computational mistakes

Answer 33

Is that correct?

Answer 34

It looks right. But I can't confirm or deny atm. I have to do my work and come back later.

Answer 35

K problem... let’s move on to the multiplication of funcs..

Answer 36

just multiply them straight up like you would with fractions

Answer 37

and same for division. Take its reciprocal and multiply

Answer 38

Much easier than adding and dividing lol

Answer 39

subtracting*

Answer 40

@hero

Answer 41

Can you check this?^^^^^

Answer 42

I'm still submitting my work for the day. I probably need another hour.

Answer 43

:/

Answer 44

Sorry bro

Answer 45

For \((f\cdot g)(x)\) you over complicated the equation, you just needed to multiply across


\(\large (\frac{f}{g})\)\((x)\) is good
