Question

Given that f(x) = −x + 4 and g(x) = −2x − 3, solve for f(g(x)) when x = 2.

Answer 1

y=−x+4 and gx=−2x−3

Answer 2

yeah? @123AB456C

Answer 3

YEP!:) go to mathpapa and go to the algebra calculator!:):)

Answer 4

i wanna learn how to do it...

Answer 5

like a first step calculi the g(2)=? and after this just calculi the f(g(2)) = ?

Answer 6

Hi there

Answer 7

So when you get a f(g(x)) that means you are putting the function g into f, so always work your way from inside to outside

Answer 8

yes in this case sure - ok. ?

Answer 9

So start with you g function and put it into f like this... -(-2x-3)+4 so your just putting in g for the x

Answer 10

Than distribute and put 2 in for x and than add it all up and you should get answer

Answer 11

Do you understand?

Answer 12

no - i have said first you calculi the value of g(2) = ? and after that you just calculi the f(g(2)) so g(2) you get a number - ok ?

Answer 13

Whats your answer?

Answer 14

@jhonyy9

Answer 15

nicole can you calculi the g(2) = ?

Answer 16

I think you get the same answer either way the way I did it I got 11

Answer 17

Your way is a lot easier though @jhonyy9 :)

Answer 18

g(2) = -7 so this mean that f(-7) = -(-7)+4 = ?

Answer 19

yes @kayders1997 ?

Answer 20

Yes that what I got

Answer 21

*thats

Answer 22

Nicole - do you understand it now ?
