**Spider Man**, Thursday, March 17, 2011 at 9:56pmTo compute for dy, you use the equation dy=f'(a)*dx where f'(a) is the derivative of the function given.

So dy=(4-2x)*dx Plug in the values

dy=(4-2(4))*(-.2)=? SOLVE

To find Δ y, you use the equation

Δy=f(x-Δx)-f(x) Plug in the values

Δy=(4(4.2)-(4.2)^2)-(4(4)-4^2)=? SOLVE
