Question

f(x)= sqrt(x+2) ; g(x) = 8x - 6

Find f(g(x)).

Answer 1

\[f(g(x)) \implies f(8x - 6) \implies \sqrt{8x - 6 + 2} \]

Answer 2

Does that help?

Answer 3

You're awesome

Answer 4

Thanks so much!

Answer 5

You can simplify that a little more.

Answer 6

Is \[\sqrt{}8x-4\] the simplest form?

Answer 7

I'm guessing no...

Answer 8

Yeah, that is.

Answer 9

You can also factor if needed

Answer 10

It's none of my answer choices/options though :/

Answer 11

What are the choices?

Answer 12

8 sqrt (x-4) is one option

Answer 13

2 sqrt (2x + 1) is another

Answer 14

2 sqrt (2x - 1) is another

Answer 15

\[\sqrt{8x - 4} \implies \sqrt{2 \times 2(2x - 1)} \implies \cdots\]

Answer 16

\[f(x)=2\sqrt{2x-1}\]
Is that the answer then?

Answer 17

Yes!

Answer 18

Yay!

Answer 19

Thanks again :)

Answer 20

Except that is \(f(g(x)) \)

Answer 21

You're welcome again

Answer 22
