Question

In exercise problems 7 – 15, use the graph to find the limits (if it exists). If the limit does not exist, explain why?

`lim_(x -> 2) f(x)` where `f(x) = {{:(4 - x",", x ≠ 2),(0",", x = 2):}`

Graph

Solution

`f(x) = {{:(4 - x",", x ≠ 2),(0",", x = 2):}`

To find `lim_(x -> 2) f(x)`

From the figure the value of the function at x = 2 is y = f(2) = 2

∴ `lim_(x -> 2) f(x)` = 2
