2. (a) What is the slope of the line through (-2,4) and (x, y) for y = x' when; i. x = -1.98? ii. x = -2.03? iii. x = -2+h? (b) What happens to this last slope when h is very small (close to 0)? (c) Sketch the graph of y = x for x near -2.3. Use the graph below to determine the limits. (a) lim f (2x) (c) lim f (2x -5) (b) lim f(x -1) (d) lim f(4 + x) x-+2 y f(x) 2 X -1
