Learn how to find the vertical asymptote

The video tutorial explains how to find vertical asymptotes by setting the denominator of a function equal to zero. This concept is crucial for understanding limits in the next chapter. Vertical asymptotes occur at values not in the domain, specifically where the denominator equals zero. The tutorial provides a step-by-step guide to finding these asymptotes, concluding with an example where x equals 4 is identified as a vertical asymptote.

What is the first step in finding a vertical asymptote?

• Integrate the function

• Find the derivative of the function

• Set the denominator equal to zero

• Set the numerator equal to zero

Why can't we divide by zero in mathematics?

• It results in a complex number

• It results in a positive number

• It results in a negative number

• It results in an undefined value

When do vertical asymptotes occur in a function?

• When the numerator is zero

• When the denominator is zero

• When both numerator and denominator are zero

• When the function is linear

What value of x is identified as the vertical asymptote in the example?

• x = 6

• x = 4

• x = 2

• x = 0

What should you do after setting the denominator equal to zero to find the vertical asymptote?

• Multiply both sides by zero

• Add a constant to both sides

• Solve for x

• Divide both sides by zero
