Sketch the graph of a function that satisfies all of the given conditions: lim f (x) = 1 lim f (x) = 1 lim f (x) = 2 f (0) = 1 x0 x1 x0+ f (x) is undefined 3. Use the limit laws to find the following limits. Justify each step. (a) lim (x2 + 3)(x  4)
x3 (b) lim (c) lim x2 3 x2 x 8 x1 x+ 1 x 6 4. Find the following limits. You don't need to justify each step, but remember to show work. (a) lim (b)
x+3 2 x3 x 9 lim 1+x1 x x0 5. Use the Squeeze Theorem to show that
x0 lim x2 sin (1/x) = 0 3x2 + 2 is continuous at x = 5 7. Find an equation of the tangent line to y = 2x + 1 at the point (4,3). 6. Show that f (x) = ...
