Product rule for exponents To multiply exponential expressions that have the same base, add the exponents and use the sum as the exponent of the shared base.
Product to power rule for exponents To raise a product to a power, separately raise each factor in the product to that power.
Quotient to power rule for exponents To raise a quotient to a power, separately raise the numerator and the denominator in the quotient to that power.
Quotient rule for exponents To divide exponential expressions that have the same base, subtract the exponent in the denominator from the exponent in the numerator and use the difference as the exponent of the shared base.
Power rule for exponents To raise an exponential expression to a power, multiply the exponents and use the product as the exponent of the base.
Initial value The value of a function that corresponds to the y-intercept of the function’s graph.
y-intercept The point at which a graph intersects the y-axis.
Growth rate The measure of how a function changes over a specified interval.
Coefficient The number before a variable.
Base The repeated factor in an exponential expression.
Exponential growth function A function of the form y=a·b^x for which y-values increase as x-values increase.
Exponential decay function A function of the form y=a·b^x for which y-values decrease as x-values increase.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
