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 -> 1) f(x)` where `f(x) = {{:(x^2 + 2",", x ≠ 1),(1",", x = 1):}`

Solution
`f(x) = {{:(x^2 + 2",", x ≠ 1),(1",", x = 1):}`
To find `lim_(x -> 1) f(x)`
From the graph the value of the function is y = f(1) = 3
∴ `lim_(x -> 1) f(x)` = 3
