Q. If $y=x^4-10$ and if $x$ changes from $2$ to $1.99$, what is the change in $y$.

Q. Let $f\left(\frac{x+y}{2}\right)=\frac{f\left(x\right)+f\left(y\right)}{2}$ and $f^{\prime }\left(0\right)=3$ and $f\left(0\right)=5$. Find $f^{\prime \prime }\left(x\right)$. (where $y$ is independent of $x$), when $f\left(x\right)$ is differentiable.

Q. Let $y=y\left(x\right)$ be the solution of the differential equation $(x-x^3)dy=(y+y{x}^2-3x^4)dx,$ $x>2.$ If $y\left(3\right)=3$, then $y\left(4\right)$ is equal to
