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)) ?

lavalavaBest 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

then just add them x^24+x+2 = ?

okay so what is f(x)=4x1 g(x)=5x^2 which is equal to (fºg)(x)?

hartnnBest ResponseYou've already chosen the best response.2
for (fog)(x) , replace 'x' in f(x) by g(x) = 5x^2

yup, that will be 20x^21

and then what is f(x)=4x7 g(x)=x+3 what is the function of (gºf)(4)
 one year ago

hartnnBest 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

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

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

hartnnBest 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 ?

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

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

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

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

hartnnBest 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 ?
