recent question - help me ?

Answer 1

this one is -40

Answer 2

-36??

Answer 3

\[f(0)=6\]
\[g(6)=6^3=216\]

Answer 4

whooops mrjoselon is right and i am wrong. help2 is -36 not -40 sorry

Answer 5

is ok. i need helpme3 now.

Answer 6

helpme3 answer is 216

Answer 7

Answer 8

new one :) <3

Answer 9

its 2

Answer 10

you appear to have posted this same exact question about 40 times by now

Answer 11

seriously right? it's not that hard...

Answer 12

\[g(30)=\sqrt{30-5}=\sqrt{25}=5\]
\[f(5)=2\times 5-8=10-8=2\] so answer is 2

Answer 13

nothing that hard when you know how to do it.

Answer 14

thanks so much satellit73 ur great <3 but i really need help /:

Answer 15

4x^4 + 1

Answer 16

\[f\circ g(x)=f(g(x))=f(x^4)=4x^4+1\]

Answer 17

\[f\circ g(x)=f(g(x))=f(x^3)=-4x^3+7\]

Answer 18

<333

Answer 19

you must be done by now yes?

Answer 20

no /: i have 10 questions. im only on 7

Answer 21

or at least have the idea of what to do . first get rid of the little circle
\[f\circ g(x)=f(g(x))\] then replace g(x) by whatever it is, in this case
\[f(x^2)\] and the replace the x in f(x) by x^2 to get
\[9x^2-5\]

Answer 22

ok first find
\[f(0)\] what do you get?

Answer 23

1 :) ?

Answer 24

right! then find
\[g(1)\] and you get...

Answer 25

1 ? :D

Answer 26

you win. that is the answer. next...

Answer 27

yay! haha. so how do we do this one?

Answer 28

ah now we have to think. but not too much

Answer 29

:( you can help me?

Answer 30

you have
\[f(x)=h(g(x))=h(8x^4-3)\] yes?

Answer 31

yes :) <3

Answer 32

and also you know that
\[h(8x^4-3)=(8x^4-3)^2\] yes?

Answer 33

yes :D

Answer 34

so what did h say do do to the input?

Answer 35

it said to cube it! in other words...
\[h(x)=x^3\]

Answer 36

okay what do we put in for x?

Answer 37

oops cube, not square. i made a typo above. so first you do g which says
\[g(x)=8x^4-3\] and then you do h which says cube the result

Answer 38

she still has no idea what to do dude

Answer 39

i don't understand what you mean "what do we put in for x?"

Answer 40

no no i miss understood continue on. im kinda understanding.

Answer 41

i guess you have to put in
\[x^3\]

Answer 42

im sorry im not so bright .. gsh . but im trying

Answer 43

\[f(6)\]?

Answer 56

Answer 57

right. now guess what we need? we need
\[g(6)\]

Answer 58
