The function is \"f.

\

\"fraction                (Apply derivative)

\

\"f        (Apply General power rule)

\

\"f          (Differentiate \"9)  

\

\"f                        (Apply General power rule)

\

To find slope at the point (1, 4)

\

So, \"f                   (Graph on the point)

\

\"m

\

To find the tangent line use point-slope form.

\

\"left                         (point-slope form)

\

\"left                        (Substitute \"y)

\

\"3                          (Multipil each side by 3)

\

\"3                                (Add 12 to each side)

\

\"Syntax                                (Divide each side by 3)

\

\"\"

\

Therefore the tangent line is \"Syntax.

\

The tangent line to the graph of the function at the given the point.
