Basic Exponential Functions

Which is the basic form of an exponential function?

Which is the basic form of a linear function?

Describe the function:

• exponential growth

• exponential decay

Describe the function:

• exponential growth

• exponential decay

Write the function for the following table:

• f(x) = 2x+1

• f(x)= x+2

Linear, exponential, or neither?

y = 4 + 2x

• Linear

• Exponential

• Neither

Linear, exponential, or neither?

y = 4(3)^x

• Linear

• Exponential

• Neither

What is the y-intercept of the function?

• 2
• 3
• 1
• -2

f(x)= b^x

^{when b > 1}
