If `f(x) = 2e^x - c lnx` monotonically increases for every `x in (0, oo)`, then the true set of values of c is

If f(x)=2e^(x)-c ln x monotonically increases for every x in(0,oo), then the true set of values of c is

If f(x) = x^(3) + (a – 1) x^(2) + 2x + 1 is strictly monotonically increasing for every x in R then find the range of values of ‘a’

If f(x)=2e^(x)-ae^(-x)+(2a+1)x-3 monotonically increases for AA x in R, then find range of values of a

if f(x) =2e^(x) -ae^(-x) +(2a +1) x-3 monotonically increases for AA x in R then the minimum value of 'a' is

if f(x) =2e^(x) -ae^(-x) +(2a +1) x-3 monotonically increases for AA x in R then the minimum value of 'a' is

if f(x) =2e^(x) -ae^(-x) +(2a +1) x-3 monotonically increases for AA x in R then the minimum value of 'a' is

If cos^(2) x - (c - 1) cosx + 2c ge 6 for every x in R , then the true set of values of c is

If the function f(x)=(x^2)/2+lnx+a x is always monotonically increasing in its domain then the least value of a is 2 (b) -2 (c) -1 (d) 1

If the function f(x)=(x^2)/2+lnx+a x is always monotonically increasing in its domain then the least value of a is 2 (b) -2 (c) -1 (d) 1
