Question

Which of the following is not a mathematical statement?

• A. Negation of statement $p$ is defined as $\sim p$
• B. $x^2-4x+3=0$
• C. $y=e^x$ is not continuous in $[0,2]$
• D. $5$ is an odd number.

Answer 1

The correct option is B $x^2-4x+3=0$

$B)$
For $x=1$ or $3$, given statement has truth value $T$.
For any other value of $x$, we have truth value as $F$.
Therefore, option $B)$ is not a statement

All the rest of the options have truth values as either $T$ or $F$ but not both, hence rest are mathematical statements.
