Find the value of each of the following polynomials at the indicated value of variables : $q(y)=3 y^{3}-4 y+\sqrt{11}$ at $y=2$

Option A

Option B

Option C

Option D

Solution

$q(y)=3 y^{3}-4 y+\sqrt{11}$

The value of the polynomial $q(y)$ at $y=2$ is given by

$q(2)=3(2)^{3}-4(2)+\sqrt{11}=24-8+\sqrt{11}=16+\sqrt{11}$
