Given  $A=\{x^2:x\in R\},B=\{{\log }_2^{3+x^2}:x\in R\}andC=\{-x^2+3x-2:x\in R\}$
Given three functions $f\left(x\right),g\left(x\right),h\left(x\right)$ with domain D, where D is $A\cup B\cup C$. The given functions will follow the inequality $f\left(x\right)\le g\left(x\right)\le h\left(x\right)\forall x\in D-\left\{\alpha \right\}$,where $\alpha$ is fixed positive integer.
And  $\underset{x\to \alpha }{\lim }f\left(x\right)=\underset{x\to \alpha }{\lim }h\left(x\right)=landf\left(\alpha \right)=h\left(\alpha \right)=l$
then which of the following is/are not INCORRECT?
