Interpreting A and B in Exponential Functions

• • The a value of 500 is the amount of medication at time t, and the b value of 1/2 represents that it decreases every half hour.

• The a value of 500 times the b value of 1/2 is always the amount of medication that will remain in the body.

• The a value of 1/2 represents the original amount of medication, and the b value of 500 represents that for every time interval, t, the amount of medication increases by 500.

• The a value of 500 represents the original amount of medication, and the b value of 1/2 represents that for every time interval, t, the amount of medication decreases by half.

• When the observation began, there were 2 bacteria colonies and the number of bacteria colonies increased by a factor of 3 for every time interval, t.

• When the observation began, there were 3 bacteria colonies and the number of bacteria colonies increased by a factor of 2 for every time interval, t.

• • The final number of bacterial colonies is found by multiplying the 2 original colonies by 3.

• After 3 minutes, there are 2 bacteria colonies.

• The a value of 0.2 represents that for each elapsed year since its purchase, the value of the boat decreases by 80%, and the b value of $25,600 represents the original cost of the boat.

• The a value of $25,600 represents the original cost of the boat, and the b value of 0.2 represents that for each elapsed year since its purchase, the value of the boat decreases by 80%.

• The a value of 0.2 represents that for each elapsed year since its purchase, the value of the boat decreases by 20%, and the b value of $25,600 represents the original cost of the boat.

• The a value of $25,600 represents the original cost of the boat, and the b value of 0.2 represents that for each elapsed year since its purchase, the value of the boat decreases by 20%.

• The a value of $150 represents the value of the painting in 1926, and the b value of 1.3 represents that for each elapsed year since 1926, the value of the painting increases by 130%.

• The a value of $150 represents the value of the painting in 1926, and the b value of 1.3 represents that for each elapsed year since 1926, the value of the painting decreases by 30%.

• The a value of $150 represents the value of the painting in 1926, and the b value of 1.3 represents that for each elapsed year since 1926, the value of the painting increases by 30%.

• The a value of 1.3 represents that for each elapsed year since 1926, the value of the painting increases by 30%, and the b value of $150 represents the value of the painting in 1926.
