Let
f(x)
 be the function
f(x) = 
−5x2  for  x ≤ 2
−4 − x  for  x > 2
Compute the right- and left-hand limits at
x = 2.

lim x→2+ f(x) =  Incorrect: Your answer is incorrect.
 lim x→2− f(x) =  Incorrect: Your answer is incorrect.


Determine whether
f(x)
 is right-continuous, left-continuous, continuous, or neither at that point.
