Answer

$d(C, E) = 3$

Work Step by Step

$d(C, E)$ represents the distance between the points C and E on a number line. If the coordinates of C and E are $c$ and $e$, respectively, then: $d(C, E) = |c-e|$ Based on the given number line, the coordinates of C and E are $0$ and $3$, respectively. Use the formula above to obtain: $d(C, E) = |0-3| = |-3| =3$ Thus, $d(C, E) = 3$
