\

The slope of the tangent at a point $\"\"$ is $\"\"$ .

\

Hence $\"\"$ .

\

Anti derivative of $\"\"$ is $\"\"$ .

\

The antiderivative of $\"\"$ is

\

$\"\"$

\

$\"\"$ , where $\"\"$ is a constant.

\

The function $\"\"$ is passes through the point $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Therefore the obtained function is $\"\"$ .
