Intro Graphing Exponential Functions

Which of the following is an increasing exponential function whose y-intercept is 50?

• y = 50(.05)^x

• y = 50x - 4

• y = (2)^x + 50

• y = 50(1.4)^x

Does the function represent exponential growth or decay?

• Decay

• Growth

Identify the y-intercept of the graph of the exponential function: y=3\left(\frac{1}{2}\right)^x

• (3,0)

• (1/2, 0)

• (0,0)

• (0,3)

What is the intercept of the exponential function?

What function is present? 

• Absolute Value

• Exponential Decay

• Linear Equation

• Exponential Growth

What is the y-intercept of the function?

• 2

• 3

• 1

• -2

In the following decreasing exponential graph

• the base is greater than one

• the base is between 0 and 1

• the base is zero

• the base is a negative value

What is the domain and range of the function y=2^x ?
Use the graph to help!

•  Domain: −∞<x<∞
  Range: y>0

• Domain: −∞<x<∞
  Range: y>1

• Domain: −2<x<∞
  Range: y>0

• Domain: −∞<x<∞
  Range: y>0

This is an example of....

• an increasing exponential function

• a decreasing exponential function

• an increasing linear function

• none of the above
