The function is
.
(Apply derivative)
(Apply General power rule)
(Differentiate
)
(Apply General power rule)
(Simplify)
To find slope at the point (1, 4)
\So,
(Graph on the point)


To find the tangent line use point-slope form.
\
(point-slope form)
(Substitute
)
(Multipil each side by 3)
(Add 12 to each side)
(Divide each side by 3)
Therefore the tangent line is
.
The tangent line to the graph of the function at the given the point.
