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 finction value, or state that the limit or function value does not exist. 34) a. lim f(x) -) -1 Please explain how these

Solution

a) x---> 1- lim f(x) as x approaches 1- which means from left side

we can see the graph which is applicable is y =1

So, x---> 1- lim f(x) = 1

b) Value of f(x) at x =1

we can see the black dot at x=1 is on the graph which passes though x =1 and y=2

y=1 does not pass through x =1

f(1) = 2
