Question:

Let y (x2 + 4) = 8

a. Use implicit differentiation to find dy/dx.

b. Find equations of all lines tangent to the curve y(x2 + 4) = 8 when y = 1.

c. Solve the equation y(x2 + 4) = 8 for y to find an explicit expression for y and then calculate dy/dx.

d. Verify that the results of parts (a) and (c) are consistent.
