How would you describe the rate of change of these functions?

• Both functions have constant rate of change because they are exponential.

• Both functions have a variable rate of change because they are both exponential.

• A has a constant rate of change because it is linear and B has a variable rate of change because it's exponential

• A has a constant rate of change because it is quadratic and B has a variable rate of change because it's exponential

What is the exponential equation for the graph?

• y=40(3/2)^x

• y=40(1/2)^x

• y=40(2/3)^x

When do we have growth?
f(x) = (a)(b^x)

• a < 1

• b > 1

• 0 < b < 1

• a > 1
