The cost of producing a double filter respirator full face masks is c(x) = 15+ 10x a² (in dollars). (a) Using the definition of the derivative from lectures, compute the marginal cost when 4 masks have already been produced. (b) Compare this to the actual extra cost for producing a 5th mask. (c) Work out the equation for the tangent to the graph of c() at x = 4.
