Given f (x) = -x2 - 4x +3. a. Evaluate f (-4) and f(-3).
b. Use the intermediate value theorem to show that there exists at least one value of x for which f (x) = 5 on the interval (-4,-3).
c. Find the value(s) of x for which f (x) = 5 on the interval (-4,-3].

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
