Any function f(x) is an increasing function in [a,b] if :
(A) x1,x2∈[a,b],f(x1)≥f(x2) if x1<x2
(B) x1,x2∈[a,b],f(x1)≥f(x2) if x1>x2
(C) (A) x1,x2∈[a,b],f(x1)≤f(x2) if x1<x2
(D) (A) x1,x2∈[a,b],f(x1)<f(x2) if x1>x2

If the total cost and total revenue of a company that produces and sells $x$ units of a particular product are $C(x) = 5x + 350$ and $R(x) = 50x - x^2$ respectively, then which of the following is/are the breakeven values: (A) $x = 10$ (B) $x = 25$ (C) $x = 45$ (D) $x = 30$ Choose the correct answer from the options given below:
The supply function of a commodity is P = $x^3+2x+18$. When 4 units of commodity are sold , then producer surplus is:
The demand function P for maximising a profit monopolist is given by P=274-x², while the marginal cost is 4+3x for x units of commodity. The consumer surplus is
If $y = e^{\frac{1}{2}\log(1+ \tan^2 x)}$, then $\frac{d^2y}{dx^2}$ is equal to:
If the random variable X follows the Poisson distribution such that P[X = k] = P[X = k+1], then the mean value of X is:
