words what the function machine is doing.<br />
a 1, 2, 3, 4, 5 4, 5, 6, 7, 8<br />
b 1, 2, 3, 4, 5 11, 12, 13, 14, 15<br />
c 2, 4, 6, 8, 10 6, 12, 18, 24, 30<br />
d 10, 20, 30, 40 5, 10, 15, 20<br />
e 10, 11, 12, 13 5, 6, 7, 8, 9<br />

j 3, 6, 9, 12, 15 1, 2, 3, 4, 5<br />
Challenge!<br />
This<br />
machine<br />
is multiplied<br />
by six<br />
adds 3<br />
Viewing sample<br />
Write function machine questions with<br />
missing functions. Give them to a friend to solve.<br />
Remember to write the missing functions on a<br />
