Question

PLEASE HELP! I really do not understand!

Answer 1

Answer with explanation:

When you will look at the function given in the graph, the function approaches to , +2 , from both sides of the line that is from,-4 , it approaches to +2, and from right side of line that is , +4 , it approaches to +2.

→When function approaches from left of line to point , x=2, we get, y= 4.

→And, when function approaches from right of line that is from , x=4 it terminates at, x=2.The value of function at , x=2 from right is , that is , y=-4 .

→→So, LHL(Left Hand Limit, at x=2 , is)

    $\lim_{x \to 2^{-} f(x)=4}\\\\ \text{RHL(Right Hand Limit, at x=2 , is)} \lim_{x \to 2^{+} }f(x)=-4$

Answer 2

Answer:

See below.

Step-by-step explanation:

Limit of f(x) as x --->  2- (that is 2 from the left)    = 4.

Limit of f(x) as x ---> 2+  (that is 2 from the right) = -4.
