    f(x) = f(t+1) it means that x = t+1

    so for your function f(x) = 2x+1 and we're asked f(t+1). that means that our x = t+1. So just plug that into our function f(t+1) = 2(t+1)+1 and solve

    ohhh so is it okay to still have a variable, in this case t, in the solution?

    so just solve this part 2(t+1)+1 and that will be our f(t+1)

    distribute the 2 for (t+1) 2(t)+2(1)+1 and combine like terms/simplify
