(a) State the limit de?nition of the derivative f'(x).

(b) Using the limit de?nition of the derivative, compute f'(x) when f (x) = x².

2. Solve the following equations. When applicable, write your answer in interval notation.

(a) log(2x 3) = 0 (Write your answer as a whole number.)

(b) e^_ex= 4

(d) x² + 2x ≤ 3

3. Evaluate the following limits and justify your answer. DO NOT use L'Hospital's rule.

(a) lim _x->Π4tan(x)

4. The position of a particle moving along a straight line is given by

s(t) = 2t³+ 3t² - 12t

(a) Find the velocity and the acceleration of the particle.

(b) Determine when the particle is moving forward (i.e. in the positive direction) and when the particle is moving backward (i.e. in the negative direction). Write your answer in interval notation.

(c) Sketch the motion of the particle on the line below, and ?nd total distance traveled by the particle after time t = 2.

5. (a) Dierentiate: f (x) = (x³ + 1)¹⁰

(d) Dierentiate via logarithmic dierentiation: f (x) = x^log(x)
