If y = ax . b2x - 1, then is
y2
D.
Given,
Taking log on both sides, we get
On differentiating, we get
Again, differentiating, we get
If , then
f(x) is continuous and differentiable for all x in its domain
f(x) is continuous for all x in its domain but not differentiable at x = ± 1
f(x) is neither continuous nor differentiable at x = ± 1
None of the above
Let f(x + y) = f(x) f(y) and f(x) = 1 + sin(2x) g(x) where g(x) is continuous. Then, f'(x) equals
f(x) g(0)
2f(x) g(0)
2g(0)
None of the above
For the curve y = xe, the point
x = - 1 is a point of minimum
x = 0 is a point of minimum
x = - 1 is a point of maximum
x = 0 is a point of maximum
