6. Suppose f(x) = 2* – 4 and g(x) = x – 2. Find the equa- tions of the tangent lines to these functions at x = 2. Then argue graphically that it would be reasonable to think f(x) as x → 2 might be g(x) that the limit of the quotient equal to the limit of the quotient of these tangent lines as x → 2.
