10.
Show the algebra and calculus required to prove
(The limit as x approaches 2 of the ratio of the quantity the x squared increased by
triple x then decreased by 10 and the quantity of x decreased by two, equals seven).
11.Explain in words why the limx
0 (1/x) doesn't exist?
The derivative of the quotient of two functions equals the derivative of the
first times the second minus the derivative of the second times the first all divided by the second squared.
