Question

Assertion :$\text{Consider the function}f\left(x\right)={\log }_c(a{x}^3+(a+b)x^2+(b+c)x+c)$.

$\text{Domain of the functions is}$ $(-1,\infty )\sim \{-(b/2a\left)\right\},$ where $a>0,b^2-4ac=0$ Reason: $\text{Consider the function}f\left(x\right)={\log }_c(a{x}^3+(a+b)x^2+(b+c)x+c)$.

$a{x}^2+bx+c=0$ has equal roots when $b^2-4ac=0$

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Assertion is correct and reason is also correct but not the correct explanation of assertion

option (B) is correct
