If `f(x)={(x^2-16)/(x-4)\ \ \ ,\ \ \ if\ x!=4k\ \ \ ,\ \ \ if\ x=4` is continuous at `x=4` , find `kdot`

Text Solution

Verified by Experts

(i) A function f(x) is said to be continuous at a point x=a of its domain, if` lim_(x→a)`f(x) = f(a)
`f(x)={(x^2-16)/(x-4)` if `x!=4`
`=k, if x=4}`
`lim_(x→a)f(x)=f(4)`
`=>lim_(x→a)(x^2-16)/(x-4)=f(4)` ...
