Question

Given the parent functions f(x) = 5x − 1 and g(x) = 3^x − 9, what is g(x) − f(x)?

Answer 1

A.) g(x) − f(x) = 3^x − 8 − 5^x
B.) g(x) − f(x) = 3^x − 10 − 5^x
C.) g(x) − f(x) = −2^x − 8 − 3^x<--------- M answer
D.) g(x) − f(x) = −2^x − 10 − 3^x

Answer 2

You're given these two functions?
\[\Large f(x) = 5x-1\]
\[\Large g(x) = 3^x - 9\]
or is it something else?

Answer 3

Yes thats it

Answer 4

wait, it's 5x or 5^x ?

Answer 5

just 5x

Answer 6

hmm strange. Your answer choices don't have 5x. They only have 5^x

Answer 7

This is what I get if it was f(x) = 5^x - 1

\[\Large f(x) = 5^x-1\]
\[\Large g(x) = 3^x - 9\]
Subtract the functions like this
\[\Large g(x) - f(x) = [g(x)] - [f(x)]\]
\[\Large g(x) - f(x) = [3^x-9] - [5^x-1]\]
\[\Large g(x) - f(x) = 3^x-9 - 5^x+1\]
\[\Large g(x) - f(x) = 3^x+(-9+1) - 5^x\]
\[\Large g(x) - f(x) = 3^x-8 - 5^x\]
The answer is actually choice A. That is assuming f(x) = 5^x - 1 is correct

Answer 8

yeah your right i have it wrong

Answer 9

Given the parent functions f(x) = 5x − 1 and g(x) = 3^x − 9, what is g(x) − f(x)?


g(x) − f(x) = 3^x − 8 − 5x
g(x) − f(x) = 3^x − 10 − 5x
g(x) − f(x) = −2x − 8 − 3^x
g(x) − f(x) = −2x − 10 − 3^x

Answer 10

im sorry :/

Answer 11

that's ok

Answer 12

so the answer i think is c

Answer 13

Is this still the same question? If so, then I show how the answer is A

Answer 14

yes its still the same question, i just have the x's in the wrong places

Answer 15

what do you mean? Can you post a screenshot of the problem?

Answer 16

ok I see now

Answer 17

it is question 1

Answer 18

\[\Large f(x) = 5x-1\]
\[\Large g(x) = 3^x - 9\]
Subtract
\[\Large g(x) - f(x) = [g(x)] - [f(x)]\]
\[\Large g(x) - f(x) = [3^x-9] - [5x-1]\]
\[\Large g(x) - f(x) = 3^x-9 - 5x+1\]
\[\Large g(x) - f(x) = 3^x+(-9+1) - 5x\]
\[\Large g(x) - f(x) = 3^x-8 - 5x\]
So the answer is still choice A

Answer 19

okay i understand it now thank you soo much for taking the time to help me!

Answer 20

no problem
