For what value of k is the following ...

For what value of `k` is the following function continuous at `x=2` ? `f(x)={2x+1\ \ \ ;\ \ \ if\ x<2k\ \ \ ;\ \ \ x=2 3x-1\ \ \ ;\ \ \ x >2`

Text Solution

Verified by Experts

As f(x) is continuous at `x=2` `lim_(x→2+)​f(x)`
`=lim_(x→2+)​(3x−1)`
`=3×2−1`
`=6−1`
`=5`
And `lim_(x→2−)​f(x)`
