If #f(x) = 3x + 1#, then what is f(2)?

Answer 1

To find ( f(2) ) when ( f(x) = 3x + 1 ), substitute ( x = 2 ) into the function. ( f(2) = 3(2) + 1 = 6 + 1 = 7 ). Therefore, ( f(2) = 7 ).

#f(x)= 7#

You are trying to find what f(x) is when x is 2, and x is equal to what you are trying to find.

#f(2)=3(2)+1#

#f(2)=6+1#

#f(2)= 7 #

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
