Notice that f(x) is only defined over the intervals 0 ≤ x < 3 and 3 < x ≤ 6; that is, all real numbers x between 0 and 3, and between 3 and 6, but not including 3. Since there is no definition for f(x) at x = 3, the value of f (3) is undefined.

A flagpole casts a shadow 16.60 meters long Tim stands at a distance of 12.45 meters from the base of the flagpole such that the

This problem is solely on right triangles, wherein the Pythagorean theorem may be applied. We must first find the angle of elevation of the flagpole using Tim's height and the difference between the shadow of the flagpole and Tim's distance from the flagpole. Therefore tan a = 1.65/(16.6-12.5) where a=21.68 degrees. We use this angle to determine the height of the flagpole. tan 21.68 = x/ 16.6 where x=height of flagpole=6.6 meters.
