MCQ
StatementA(Assertion): $f(x)=2 x^3-\frac{3}{x}+7$ is a polynomial in the variable $x$ of degree 3 .
Statement R (Reason) : The highest power of $x$ in a polynomial $f(x)$ is called the degree of the polynomial $f(x)$.
  • A
    Both assertion (A) and reason ( $R$ ) are true and reason $(R)$ is the correct explanation of assertion $(A)$.
  • B
    Both assertion (A) and reason ( $R$ ) are true and reason $(R)$ is not the correct explanation of assertion (A).
  • C
    Assertion $(A)$ is true but reason $(R)$ is false.
  • Assertion (A) is false but reason $(R)$ is true.

Answer

Correct option: D.
Assertion (A) is false but reason $(R)$ is true.
(d) : $f(x)=2 x^3-\frac{3}{x}+7=2 x^3-3 x^{-1}+7$ is not a polynomial as one of the term is $-3 x^{-1}$.
$\therefore$ Assertion is false but Reason is true.
