Step 1 :

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

Rewrite the expression :

$\"\"$

Differentiate y with respect to x.

$\"\"$

The slope(m) of a tangent line at the point $\"\"$ :

Substitute $\"\"$ in $\"\"$

$\"\"$

Step 2 :

Point-slope form of a line equation $\"\"$ .

Substitute $\"\"$ and the point $\"\"$ in above equation.

$\"\"$

The equation of a tangent line is $\"\"$

Solution :

The equation of a tangent line is $\"\"$
