Intro to Exponential Functions Growth vs Decay

Is this exponential growth or decay?

• Growth, because of 7

• Decay, because of 1.2

• Growth because of 1.2

• Decay because of 7

Is the pictured graph exponential growth, exponential decay, linear growth, or none?  

• Exponential Growth

• Exponential Decay

• Linear Growth

• None of the above

What type of function is f(x) = 2^x ? 

• exponential growth 

• linear equation

• exponential decay 

• linear inequality 

Pick the equation that is exponential growth

• y=2(0.5)^x

• y = 0.5(2)^x

• y = .5x - 2

• y = 2x + .5

What function is present? 

• Absolute Value

• Exponential Decay

• Linear Equation

• Exponential Growth

Answer explanation

The function present is Exponential Decay because it represents a decreasing quantity over time.
