(a) f (x) = 5 ? 2x x+1 (b) g (x) = 2 x ? 3x ? 10 2. animated cartoon the by-line give-up the ghost without plotting points. First, state the basic serve up, then which transformations occur. ? f (x) = 1 ? 2 x + 3 3. For f (x) = 8. For what value c is the by-line function continuous on (??, ?)? cx2 + 2x x3 ? cx if x < 2 if x ? 2 9. For the function below x and g (x) = tan x, ?nd x?1 (a) (f ? g )(x) (b) The field of honor of (f ? g )(x) (a) State the points where f (x) is discontinuous. (b) Explain which part of the de?nition fails for independently value in part (a). 4. Sketch a function that satis?es all the criteria below (c) Which, if any, of these discontinuities are removable? lim f (x) = 2 x?3? lim f (x) = 2 x?3+ lim f (x) = ? x?0 f (3) = ?1 5. Find the following limits algebraically ? x+4?2 (a) lim x?0 x x2 + x ? 6 (b) lim x? 2 x?2 5x + 1 (c) lim x? 0 x + 2 10. Use the? intermediate value theorem to ratify f (x) = 3 x ? 1 + x has a root somewhere on the interval (0, 1). 11.
