Since u want to find F(x) at x=6 , U will use the Function F(x)= x^21 because x is bigger or **Equal** 6 Plug 6 in the equation so it will be F(6)=(6)^21=.....

what about f(x)=x^24; g(x)=x+2 which is equal to (f+g)(x)

U mean Find F(F(x)+g(x)) ?

lavalava Group TitleBest ResponseYou've already chosen the best response.1
no its f(x)+g(x) im not to sure but i think that might be it

hartnn Group TitleBest ResponseYou've already chosen the best response.2
then just add them x^24+x+2 = ?

lavalava Group TitleBest ResponseYou've already chosen the best response.1
okay so what is f(x)=4x1 g(x)=5x^2 which is equal to (fºg)(x)?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
for (fog)(x) , replace 'x' in f(x) by g(x) = 5x^2
 one year ago

lavalava Group TitleBest ResponseYou've already chosen the best response.1
so then : 4(5x^2)1

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yup, that will be 20x^21

is it 12?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
to get (gof)(x) replace 'x' in g(x) by f(x) and then put x=4

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yup, its 12

the graph of g(x) results when the graph of f(x)=x is shifted 3 units to the left. i think it's g(x)=x+3

in which range does 4 lie ?
 one year ago

lavalava Group TitleBest ResponseYou've already chosen the best response.1
the middle one and the last one
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
not the last one, x>2 means x cannot be 4 so only middle one. put x= 4 in middle function, what do u get ?

hartnn Group TitleBest ResponseYou've already chosen the best response.2
nopes, its 4th. put these values, x=0,0.5,1,1.5,..., find g(x) u will get it

f(x)=2x+5 g(x)=3x^2 which is equal to (fºg)(x)? i tried it and i got 3x^2+2x+5 but i think it's wrong....
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
put x= 3x^2 in f(x) 2(3x^2)+5 = ?

omg you make it easier to understand hahaha

more questions ? i need to go...

f(g(x)) = 2/(x1) ok? for which values is denominator = 0 ??
 one year ago

lavalava Group TitleBest ResponseYou've already chosen the best response.1
no the ones i put up last were the options
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
i know. denominator should not be 0 x1 should not be 0 for x=1, 11=11=0 for x=1, 11=11=0 so xx≠1, x≠1 got it ?
