Can R Model Fits Have A Constant?

I am trying to add a constant to my model 

 exponential <- lm((log(fallpercent$n_activities)~ 
 ((fallpercent$percentabovebelow1 )+3))

This produces the error

Error in terms.formula(formula, data = data) : 
  invalid model formula in ExtractVars.

I am trying to create a function with the equivalent of y = ex+3.

Ideas on how to do so?
