1. He deposited 10 dollars in the bank and it grew at a rate of 2%25
2. Bacteria starts with a population of 10 and doubles every day.
3. He swam up at a rate of 2 inchers per second and started 10 feet below the ground
4. He put 10 in penny stocks but lost 2%25 each year
5. He owed the bank 2 dollars, but added 10 dollars a week to his account
6. She was 10 feet below the ground and continued to swim deeper at 2 feet per second
7. y = mx %2b b
8. Her father gave her 10 dollars. She added 2 dollars a wekk.
9. She had 2 dollars in penny stocks and it grew at 10%25 each year
10. Building blocks start at 2 block and we add 10 blocks in a second
11. constant rate

Answers:
0. y = 10 (0.98)^x
1. y = -2x - 10
2. y= 2(1.10)^x
3. multiplying or dividing by a certain amount over intervals
4. y = 2(0.90)^x
5. y = -2x %2b 10
6. y = 10 (2) ^ x
7. Linear Function
8. adding or subtracting the same amount over intervals
9. y = 2x %2b 10
10. y = 10x - 2
11. y = 2x - 10
12. y = 10 (1.02) ^ x
13. y = 10x %2b 2
14. Exponential Function
15. y = -10x %2b 2
