Question

Refer to functions $m$ and $n$ . Find the function $( n \cdot m ) ( x )$ and write the domain in interval notation. Write any number in the intervals as an integer or a simplified fraction.

$m ( x ) = \sqrt { x + 3 } n ( x ) = x + 5$

$( n \cdot m ) ( x ) = \square$

Billy rides his bicycle on a straight race track. When he starts sprinting he increases $2 m / s$ for every second, $s$ , he continues to drive over $9$ seconds in the race. At $9$ seconds he is traveling $10 m / s$ . He Writes the following functions to represent his speed after s seconds but he must combine them somehow:

$a ( x ) = s - 9$

$s ( x ) = 2 s + 10$

Write a composite function to represent his speed $s$ seconds in the race $( 3 pts ) $ .

Find out how fast he is going after $14$ seconds ( $3$ pts).
