Question

Given the parent functions f(x) = 3x + 2 and g(x) = 5x − 10, what is g(x) − f(x)?

Answer 1

g(x) is the same thing as 5x-10
f(x) is the same thing as 3x+2

The above means that if you're looking for g(x)-f(x) you simply replace g(x) and f(x) with what they are.

Answer 2

i tried using the formula f(x) - g(x) ... but when i solved it did not fit any of my choices which are
g(x) − f(x) = 5x − 8 − 3x

g(x) − f(x) = 5x − 12 − 3x

g(x) − f(x) = 3x − 8 − 5x

g(x) − f(x) = 3x + 12 − 5x

Answer 3

by solving i got -9, but that's not what they want

Answer 4

You don't have to solve it

Answer 5

Ok, I'll try to simplify what's being said even more.
f(x)=3x+2
g(x)=5x-10

g(x)-f(x)=?

Answer 6

5x - 10 - 3x + 2

Answer 7

Don't forget that -f(x) means -(3x+2)

Answer 8

g(x)-f(x)=(5x-10)-(3x+2)=5x-10-3x-2=2x-12

Answer 10

but look at my answer choices ... i'm still not understanding

Answer 11

Multiple choice questions are stupid so you'll have to rearrange your answer to fit the answers.

Answer 12

Noliec :what?i'm completely sure about mu answer

Answer 13

Yes, you're never supposed to just give the answer.

Answer 14

hirin can you break it down for me

Answer 15

What you wrote was almost correct mgarrick77

Answer 16

somebody is still incorrect ` my answer choices are
g(x) − f(x) = 5x − 8 − 3x

g(x) − f(x) = 5x − 12 − 3x

g(x) − f(x) = 3x − 8 − 5x

g(x) − f(x) = 3x + 12 − 5x

Answer 17

You have to remember though, like I said before that -f(x) is not -3x+2

Answer 18

-(3x+2) is the same thing as -3x-2

Answer 19

the 2nd choice is correct.

g(x)-f(x)= 5x-10-(3x+2)
=5x-10-3x-2
=5x-10-2-3x
=5x-12-3x

Hope this helps!

Answer 20

lol that's what i was asking ... was i suppose to add 10+2

Answer 21

okay the answer is g(x) − f(x) = 5x − 12 − 3x

Answer 23

5x-3x=2x
did u know that?

Answer 24

yes shirin
i knew that

Answer 25

can you guys continue to help me ? i want to make sure i got it

Answer 26

okay it's done

Answer 27

;)

Answer 28

Given the function f(x) = 0.3(4)x, what is the value of f−1(6)?
0.360

1.242

2.161

2.312

i guessing i suppose to plug in ... but when i took the numbers it didn't quite work

Answer 29

i have a Ti-84 calculator ... i tried to plug it in

Answer 30

You have that:
f(x)=3x+2
g(x)=5x-10

You're looking for g(x)-f(x), which is the same thing as (5x-10)-(3x+2), which is the same thing as 5x-10-3x-2, try to see how you can reformulate this to your question.

Answer 31

can we say: f(x) = 0.3(4)x=1.2x?

Answer 32

That's a better start than initially Shirin74! ;)

Answer 33

noliec:the answer of that question was found and now it's finished
we are thrying to answer the new one

Answer 34

(in terms of following the code of conduct and actually emphasizing on learning people things)
=)

Answer 35

The new question is one of the worst questions I've seen in academic history. The use of a calculator in math should be prohibited and problems designed so that you don't need one.

Answer 36

my new question is up their

Answer 37

so what should we do?

Answer 38

i tried by pluging in the f^-1(6)
