Mark (√) against the correct answer in the following: If is continuous at x = 2 then k = ?

Question

Philoid · Accepted Answer

For continuity left hand limit must be equal to right hand limit and value at the point.

Continuous at x =2.

L.H.L =

⇒ k(2-0)+5 = 2k+5

R.H.L

⇒ 2+0+1

=3

As f(x) is continuous

∴ 2k+5 = 3

K = -1.
