(a) If F(x) = 6x/(2 + x2), find F '(2) and use it to find an equation of the tangent line to the curve y = 6x/(2 + x2) at the point (2, 2). F '(2 ) = V(x) (b) Illustrate part (a) by graphing the curve and the tangent line on the same screen. y 10/ y 10/ 5 5 -10 -5 5. X 10 -10 -5 X 10 -5 -5 O -10 O 10/ 10 5 5 -10 5 5 X 10 X 5 TO
