Exploring Exponential Functions: Asymptotes, Domain, and Range

The video tutorial explains how to find the asymptote, domain, and range of exponential functions. It introduces the concept of a horizontal asymptote and demonstrates how to determine the domain and range using two graph examples. The domain is always from negative to positive infinity, while the range depends on the graph's direction relative to the asymptote.

What are the three main concepts discussed in the video?

• Asymptote, domain, and range

• Mean, median, and mode

• Slope, intercept, and range

• Derivative, integral, and limit

What is an asymptote in the context of an exponential function?

• A curve that the graph follows

• A point where the graph intersects the x-axis

• A horizontal imaginary line that goes through the y-axis

• A vertical line that the graph approaches

What is the domain of an exponential function?

• From 0 to 1

• From negative infinity to 0

• From 0 to positive infinity

• From negative infinity to positive infinity

In the first example, what is the horizontal asymptote?

• y = 0

• y = 1

• y = 2

• y = -1

How is the range of an exponential function determined?

• From the top to the bottom of the graph

• From the center to the edges of the graph

• From the left to the right of the graph

• From the bottom to the top of the graph

In the first example, what is the range of the function?

• From negative infinity to positive infinity

• From negative infinity to 0

• From 0 to positive infinity

• From negative infinity to 2

In the second example, what is the horizontal asymptote?

• y = 2

• y = -2

• y = 6

• y = -6

What is the range of the function in the second example?

• From negative infinity to -6

• From 0 to positive infinity

• From negative infinity to positive infinity

• From -6 to positive infinity
