Chapter 7 Review

• exponential growth (increasing)

• exponential decay (decreasing)

• both growth and decay

Pick the equation that represents exponential growth (is increasing).

• y=2(0.5)^x

• y = 0.5(2)^x

This graph represents:

• Exponential Growth
• Exponential Decay
• Direct Variation
• None of the above
