use the function to answer the question:
x+14 if x<7
f(x) 21 if 7 ≤x<6
x^2 1 if x ≥ 6
what is the value of f(6)?

Best ResponseYou've already chosen the best response.1Since 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=.....

Best ResponseYou've already chosen the best response.1what about f(x)=x^24; g(x)=x+2 which is equal to (f+g)(x)

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

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

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

Best ResponseYou've already chosen the best response.1and then what is f(x)=4x7 g(x)=x+3 what is the function of (gºf)(4)

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

Best ResponseYou've already chosen the best response.1the 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

Best ResponseYou've already chosen the best response.2in which range does 4 lie ?

lavalava

Best ResponseYou've already chosen the best response.1the middle one and the last one

hartnn

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

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

Best ResponseYou've already chosen the best response.1f(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....

hartnn

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

Best ResponseYou've already chosen the best response.2f(g(x)) = 2/(x1) ok? for which values is denominator = 0 ??

lavalava

Best ResponseYou've already chosen the best response.1no the ones i put up last were the options

hartnn

Best ResponseYou've already chosen the best response.2i 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 ?
