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 1

Help

Answer 2

I know It's not C

Answer 3

3^x - 9 - (5x - 1)

Answer 4

Yes

Answer 5

Any ideas?

Answer 6

just evaluate that expression?

Answer 7

I've already selected C this is my second time taking the quiz

Answer 8

I did

Answer 9

Yeah

Answer 10

look at it this way:
3^x - 9 + (-1(5x + 1))

Answer 11

So I get 3^x - 10 - 5x

Answer 12

yep.

Answer 13

I think there's something wrong with the question because apparently that's no the answer

Answer 14

oh nvm i read the question wrong mb

Answer 15

3^x - 9 + (-1(5x - 1))

Answer 16

5x - 1 not 5x + 1
sorry, i'm silly

Answer 17

Ok I just solved for 5x + 1 and got the answer as B it was right. Thanks anyway

Answer 18

yep yw
