Find the domain of the function f (x) = Restrictions on the domain : ln (x + 1) . ln (x − 2) • ln(x − 2) ￿= 0, x ￿= 3. • x + 1 > 0, x > −1. • x − 2 > 0, x > 2. Therefore the domain of f is (2, 3) ∪ (3, ∞). √ 3. Find the slope of the line tangent to the curve f (x) = x at the point (9, 3) by using the limit definition of the instantaneous rate of change. Then find the equation of this tangent line...
