This document discusses finding the slope of a tangent line at a point on a curve, finding points where tangent lines are horizontal or vertical, and proving the power rule for rational exponents.

1. What is the slope of the tangent line at (1, 2 ) on the curve

2. For the given function, find all points on the graph where the tangent lines to
the graph are: (a) horizontal, (b) vertical.

3. Proving the Power Rule for rational exponents ...
