You should use parentheses to write this expression. It could mean at least 4 different things, but as stated it means .
Evaluate the limit of 4-x/2-√x as x approaches 4
I believe that this function is in indeterminate form. I just cant seem to rewrite the function so that i can find the limit ( if it exists).
If anyone can explain how to evaluate this limit, I would be very grateful.
