Answer:
Domain: from -6 to 6, inclusive
Range: from -6 to 6, inclusive
Step-by-step explanation:
It's a circle centred at origin with radius 6
Point H shows 45 because 6.7 multiplied by each other equals 45 and 6.7 on the line is point H
6/21 I think cause you can't go down any more
Replace the letters with their given values:
6(6) - 8 / 4
Do the multiplication:
36-8 / 4
Subtract:
28/4
Divide to get the final answer :7
Answer = 7
