The table below shows values for four differentiable functions. Suppose we know the following things: b' (z) = e(x) e'(x) = a(x) a'(2) = c(a) c'(x) = b(x) 0 1 2 3 4 4 3 0 1 2 0 4 3 1 b(ac) 0 3 1 4 2 4 3 What is a(x)da? What is (b (a ) + 7 ) da? What is the equation of the tangent line to the curve y = c(x) when x = 1? Answer: y =
