The tangent of the graph of $\"\"$ at the point $\"\"$ intersects the $\"\"$ -axis at $\"\"$ .

The tangent to the graph will go through the points $\"\"$ and $\"\"$ .

Therefore need to find the slope of the line.

From the definition the slope of the tangent line is equal to $\"\"$ .

The slope of the equation $\"\"$ .

Where $\"\"$ and $\"\"$ .

$\"\"$ .

$\"\"$

Apply the integration.

$\"\"$

Therefore, the tangent is $\"\"$ .

$\"\"$

The tangent is $\"\"$ .
