Question

(a) If
F(x) = 12x/(3 + x^2),
find F '(3) and use it to find an equation of the tangent line to the curve
y = 12x/(3 + x^2)
at the point (3, 3).
F '(3) =
y(x) =

Answer 1

find the derivative using the quotient rule. that derivative will be your slope, so to find F'(3), plug in 3 where there is an x in your derivative.
To find the tangent line, remember your point slope formula?
