Look at the graph and answer each question. Does the graph show growth or decay? What is the y-intercept? What is the asymptote?

• Growth

  y-intercept: (0, 5)

  asymptote: y = 0

• Decay

  y-intercept: (0, 5)

  asymptote: y = 0

• Growth

  y-intercept: (0, 5)

  asymptote: y = 5

• Decay

  y-intercept: (0, 5)

  asymptote: x = 0

The image shows how the value of a specific car decreases over time. What was the initial value of the car?

• $12,000

• $3,000

• $75,000

• $6,000

What is the asymptote of the function?

• x = 1

• y = 1

• x = 0

• y = 0

Does the graph show an example of exponential growth or decay?

• Growth

• Decay

• The first part of the graph is growth and the second part is decay

• The graph shows neither growth, nor decay.

In an exponential function, what does the 'a' represent? 

• SLOPE

• RATE OF CHANGE

• Y-INTERCEPT

• COMMON RATIO

Is this exponential growth or decay?

• Growth

• Decay

• The graph shows decay, then growth

• Neither

What type of function is y = 7(5/4)^x?

• Exponential Growth

• Exponential Decay
