4. A laser beam travels along a straight path for a certain distance, and then bounces n times off tilted mirrors before striking a target. The laser beam travels v2 additional

centimeters each time it bounces off a mirror. When there are 5 bounces, the laser

beam travels 13v2 cm.

a. Let d (n) denote the distance the laser travels in cm as a function of the number

of bounces off a mirror, n. What does d(5) represent? What is the value of d(5)?
