It is given that an equation of the tangent line to the graph of y=g(x) at x=9 is

6x+9y=-27.

It follows that y=? is the equation of the tangent line to y=g(x^2) at x=3

and that y=? is the equation of the tangent line to y=(g(x))^2 at x=9.

6x+9y=-27.

It follows that y=? is the equation of the tangent line to y=g(x^2) at x=3

and that y=? is the equation of the tangent line to y=(g(x))^2 at x=9.
