The function is $\"\"$ and point is $\"\"$

To find the slope graph when $\"\"$ , evaluate the derivative, $\"\"$ , at $\"\"$ . $\"\"$

$\"\"$ $\"\"$

\

Now, using the point slope form of the equation of a line, you can write

\

$\"\"$ (Point - slope form)

Therefore the tangent line equation is $\"\"$ .
