The graph of a function is given Use the graph to find the i

The graph of a function is given. Use the graph to find the indicated limit and function value or state that the limit or function value does not exist. a. lim _x rightarrow 1 f(x) b. f(1)

Solution

20
a) when x approches 1 at that time the y is not defined so value does not exist since the function is discontinuous at x=1

b) f(1) means the value of y when x=1
this can be seen in graph that at x=1 our y=2
since we have a closed circle at y=2 for x=1
hence f(1)=2
