The flashcards below were created by user KattthD on FreezingBlue Flashcards. What would you like to do?


  1. Exponential Function and label the values
    • f(x) = b^x
    • b-base, constant
    • x-exponent, independent variable
  2. Given a exponential function, with no specific x, what do you do?
    You input your own values.
  3. Given a exponential function, with no specific x, what do you put your domain as?
    "all real numbers"
  4. What does the domain and range represent?
    • Domain-x value
    • Range-y value
  5. How would you write the domain?
    • D-all real numbers
    • R- {y|y>0}
  6. Exponential Growth
    • f(x) = ab^x, with a>0 and b>1
    • The function increases as x increases
  7. Exponential Decay
    • 0<b<1
    • function dcreases as x increases
  8. Is this a growth or decay function? f(x) = 1.5^x
    Growth
  9. Is this a growth or decay function? f(x) = (.8^x)?
    Decay
