Is the graph linear, exponential, or neither?

• Linear

• Exponential

• Neither

Pick the equation that is exponential growth

• y=2(0.5)^x

• y = 0.5(2)^x

Pick the equation that is exponential decay

• y=2000(0.88)

• y=0.5(1.88)

Which statement below describes the comparison of rate of change between the linear function f(x) and the exponential function g(x).

• g(x) rate of change is ALWAYS greater than f(x) rate of change.

• g(x) is NEVER greater than f(x) rate of change.

• g(x) will eventually exceed the rate of change of f(x).

• There is not enough information to compare the rate of change of f(x) to g(x).
