Q.
If a is a natural number which of the following statements is always true?
In the figure below, equation of the line PQ is
For which of the following functions is
\( \dfrac{f(a)-f(b)}{a-b} \) constant for all the numbers ‘a’ and ‘b’, where a ≠ b?
Given that \( f(a,b,c)=\dfrac{a+b+c}{3} \), then
(a) \( f(a,b,c)\ge\dfrac{\lvert a\rvert+\lvert b\rvert+\lvert c\rvert}{3} \)
(b) \( f(a,b,c)\ge\max(a,b,c) \)
(c) \( \lvert f(a,b,c)\rvert\ge\dfrac{\lvert a+b+c\rvert}{3} \)
(d) \( \lvert f(a,b,c)\rvert\le\dfrac{\lvert a\rvert+\lvert b\rvert+\lvert c\rvert}{3} \)
We are given two variables \( x \) and \( y \). The values of the variables are
\( x=\dfrac{1}{a+b} \) and \( y=\dfrac{3}{c+x} \). Find the value of the expression \( \dfrac{7y}{x} \)
(a) \( \dfrac{21(a+b)^2}{ca+cb+1} \)
(b) \( \dfrac{3(a+b)}{7ab+ac} \)
(c) \( \dfrac{7}{3(ca+cb+1)} \)
(d) None of these
If \( p=\dfrac{12-\lvert x-3\rvert}{12+\lvert x-3\rvert} \) the maximum value that ‘p’ can attain is:
Refer to the graph. What does the shaded portion represent?
