Ever hour is 25 so 25*5=125
B because it is between x: 4 and 6. And it is linear and decreasing
Rule for 1 is the rule for 1 is 14 times 3.5^x and it is exponential
The second one is is also exponential and the rule is 32 times .25^x and the last one is is linear and the rule is 5x+-4
This would be 13+2x because if x is the number, then 2 times it would be 2x and the sum means addition so it would be 13+2x
