Questions & Step-by-Step Solutions

Which of the following is a characteristic of exponential functions?
  • Step 1: Understand what an exponential function is. It is a function where the variable is in the exponent, like f(x) = a * b^x.
  • Step 2: Recognize that exponential functions can either grow (increase) or decay (decrease).
  • Step 3: Identify that the growth or decay happens at a constant percentage rate, meaning the rate of change is proportional to the current value.
  • Step 4: Conclude that this constant percentage rate of change is a key characteristic of exponential functions.
