1. Let f be the function defined by f(x) = x
2 on the positive real numbers. Find the
equation of the line tangent to the graph of f at the point (3, 9).
2. Graph the reflection of the graph of f and the line tangent to the graph of f at the point
(3, 9) about the line y = x.

I really need help on number 2!!!! It's urgent!

Find the equation of the tangent line to the graph of the function f(x)=(x^2+8)(x−2) at the point (1,−9). I thought it was re-writen as (2x^2 + 8)(x-2) then plugging in 1 for x and solving. I came up withit in slope form y = -20x - 1 but says im wrong. What steps did i miss?
