Question

1. What is the growth/ decay rate for this exponential function?

y = 100(2)^x


The second question is in the picture below. Please explain why that answer is correct because I just guessed on this without knowing why it is the answer

Answer 1

Answer:

1. The growth rate is 2

2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5

Step-by-step explanation:

The growth and decay factor in an exponential function is the number that is being multiplied to the power of x

• It is a growth rate when that number is greater than 1
• It is a decay rate when the number is less than 1
• If it's 1 then it's not growing or decaying
• If it's 0 you will have an answer of 0
