Homework 6.4 Intro to Exponential Functions

What is the y-intercept of the function?

• 2
• 3
• 1
• -2

Is this exponential growth or decay?

• Growth
• Decay

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

• SLOPE
• RATE OF CHANGE
• Y-INTERCEPT
• COMMON RATIO

Using the table below, find the equation that matches

• y = 20(2)^x

• y = 20(1/2)^x

• y = 2(20)^x

• y = 20(1.25)^x

What is the equation for the graph of the exponential function?

• y = 4(2)^x

• y = (4)^x

• y = (2)^x

• y = 2(4)^x
