Evaluate the limit at infinity with square root

The video tutorial explains how to evaluate limits of a function as X approaches both positive and negative infinity. It demonstrates the process using a specific function, showing that the limit as X approaches infinity is -2/3, while the limit as X approaches negative infinity is 2/3. The tutorial concludes by encouraging students to verify the results using a calculator.

What is the limit of the function F of X as X approaches infinity?

• -2/3

• 1/3

• 0

• 2/3

When X approaches negative infinity, what does the limit of the function F of X become?

• 2/3

• 0

• 1/3

• -2/3

Why does the limit change to positive 2/3 when X approaches negative infinity?

• Because the function is undefined

• Because negative times negative is positive

• Because absolute values are always negative

• Because the limit is always positive

What is the significance of the absolute value in the limit calculation?

• It affects the sign of the limit

• It ensures the limit is positive

• It has no effect on the limit

• It makes the limit negative

What should you do to verify the calculations discussed in the video?

• Rewatch the video

• Use a calculator

• Ignore the calculations

• Ask a friend
