Question

y = ax, where a is greater than zero but not equal to 1 and x is an exponent
1. exponential decay
2. exponential function
3. exponential growth

Answer 1

3. exponential growth

Answer 2

I disagree. I prefer 2: exponential function.

If 0 < a < 1 then a^x is exponential decay

Answer 3

You are correct. If 0 < a < 1, then y = ax^k is an exponential decay function. Thank you for catching my mistake!
