Exponential Functions

What is an exponential function?

• A function that cannot have negative values

• A function where the variable is the base

• A function where the variable is the exponent

• A function with a constant exponent

What is the value of any base raised to the zero power?

• The base itself

• 0

• 1

• Undefined

What does the base of an exponential function need to be?

• Negative

• Positive and not equal to one

• Exactly one

• Any real number

What kind of growth do exponential functions often model?

• Quadratic growth

• Linear growth

• Rapid increase or decrease

• Constant growth

What is the result of 1.5 times four to the power of three?

• 192

• 96

• 64

• 12

What is the horizontal asymptote of the function two to the X?

• Y axis

• X axis

• Y = 1

• X = 1

What happens to the function as the exponent increases in the negative direction?

• Approaches zero

• Remains constant

• Approaches negative infinity

• Becomes undefined

What does adding a number to the variable term in an exponential function do?

• Reflection across the X axis

• Horizontal shift

• Reflection across the Y axis

• Vertical shift

What effect does a negative sign before the variable have on the function?

• Reflection across the Y axis

• Reflection across the X axis

• Vertical stretching

• Horizontal stretching
