    Another F of X
    Just making sure I did this right...

    If f(x)=x squared + 1
    Find f (t+1)

    I got F (t+1) squared



    Just to let everyone know, you all are awesome for helping on these questions!! :)

    You insert the (t + 1) in for the x correctly, but didn't carry the "+ 1" on the end with it. That isn't the same "+ 1" as the one for the x. It's completely separate.

    Put parenthesis around the x in the function. Then replace that x with the (t + 1), but keep everything else. See what I mean?

    (Is that an acceptable answer, or are you also supposed to foil, combine like terms & all that?)

    Well, I'll make it clearer. I'll follow the same procedures as morgaine300, if you didn't understand her:

    So, you have:

    replace 'x' by (t + 1)



    Then you simplify.
