Shown below are six statements about functions. match each statement to one of the functions shown below which best matches that statement. 1. limx→7+f(x) and limx→7−f(x) both exist and are finite, but they are not equal. 2. the graph of y=f(x) has vertical tangent line at (7,f(7)) 3. limx→7−f(x)=−[infinity]. 4. limx→7+f(x) exists but limx→7−f(x) does not. 5. limx→7f(x)=[infinity]. 6. limx→7f(x) exists but f is not continuous at 7.
