my question is f(X + 1) = . the rule is f(X) =3X+2.
i got - 3(X + 1) +2
then i got - 3X +5

can someone explain what to do from here, im stuck

anonymous · Answer

thats it, your done, unless they are asking you to solve for x

hero · Answer

3(x+ 1) + 2 = 3x + 5

anonymous · Answer

when you sub in an expression, you often get an expression as the simplified form

thx very much i feel real dumb right about now but its watever , i guess   

<3    ; )   <3

anonymous · Answer

they r asking mi  to solve for x

anonymous · Answer

you've got f(x+1)=3x+5 but this is not an equation.  you can solve for x if you let y=0, where y=f(x+1).  is that what they mean?  solve 3x+5=0

anonymous · Answer

3x+5=0
3x=-5
x=-5/3

but i am just guess that that i what they mean
