What is another name for average rate of change?

• Slope

• Y-Intercept

• Zeros

What is the formula for average rate of change?

If the y-value are being multiplied by the same number in a table, what does that mean?

• It's an exponential function

• It's a linear function

• It's a quadratic function

• It's a rational function

• Linear

• Exponential

• Neither

• Both

• Growth

• Decay

How do you decide if a function represents exponential growth or exponential decay?

• Look at the inside of the parenthesis. If it's greater than 1, growth. If it's less than 1, decay.

• Look at the inside of the parenthesis. If it's greater than 1, decay. If it's less than 1, growth.

• Examine the sign of the exponent. If it is positive, it is exponential growth; if it is negative, it is exponential decay.

• Compare the rate of change of the function to the rate of change of the base. If the rate of change of the function is greater than the rate of change of the base, it is exponential growth; if the rate of change of the function is less than the rate of change of the base, it is exponential decay.

Which exponential function would represent the following scenario?

Suppose a culture of bacteria begins with 2000 cells and dies by 3% each year.
