Let f : R → R be defined by
f(x) = 
If f has a local minimum at x = – 1, then a possible value of k is
A
0
B
C
–1
D
1
Text Solution
Verified by ExpertsThe correct answer is:
C
f(x) = 1
f(–1) = k + 2
f(x) = k + 2
f has a local minimum at x = – 1
∴ f(–1 + ) ≥ f(–1) ≤ f(–1 – )
1 ≥ k + 2 ≤ k + 2
⇒ k ≤ – 1
possible value of k is – 1
Hence correct option is
