Question
Let $f^{\prime \prime}(x)>0 \forall x \in R$ and $g(x)=f(2-x)+f(4+x)$.Then, $g(x)$ is increasing in(A) $(-\infty,-1)$(B) $(-\infty, 0)$(C) $(-1, \infty)$(D) None of these
Step 1
Step 1: Given that $f''(x)>0$ for all $x \in R$, this implies that the first derivative of $f(x)$, denoted as $f'(x)$, is increasing for all $x \in R$. Show more…

Let $f(x)=x+1$ and $\phi(x)=x-2$, then the values of $x$ satisfying| $f(x)+\phi(x)|=| f(x)|+| \phi(x) \mid$ are (A) $(-\infty, 1)$ (B) $(2, \infty)$ (C) $(-\infty,-2)$ (D) $(1, \infty)$
The function $f(x)=|x+2|+|x-1|$ is (A) increasing in $(1, \infty)$ (B) increasing in $[1, \infty)$ (C) decreasing in (-\infty, - 2] (D) decreasing in $(-\infty,-2)$
Given that $f^{\prime}(x)>g^{\prime}(x)$ for all real $x$ and $f(0)=g(0)$, then (A) $f(x)>g(x) \forall x \in(0, \infty)$ (B) $f(x)<g(x) \forall x \in(-\infty, 0)$ (C) $f(x)<g(x) \forall x \in(0, \infty)$ (D) $f(x)>g(x) \forall x \in(-\infty, 0)$
