# [plt-scheme] Understanding lambda

I am trying to understand lambda and i have a question.
Suppose (define f (lambda(x) (+(* 3 x) 5)))
Now i have read and heard that lambda is used to define unnamed functions
now , i am confused about the value of f
ie will it be equal to the function returned by (lambda(x) (+(* 3 x) 5)) or
will be equal to the value which is computed for any value of x ie if x =1
then f =8.Any help is appreciated.
Thanks in advance
Aditya
