1. (a) Use definition (2) in the textbook (p.135) to find the slope of the line tangent to the graph of f at P. (b) Determine an equation of the tangent line at P. f(x) = P(-2, 2) 2. The following limit represents the slope of a curve y = f(x) at the point (a, f(a)). Determine a possible function f and number a; then calculate the limit. V2+ h - V2 lim h+0 h
