Q. What is the equation of the vertical asymptote of y=x+91 ? _____
Identify vertical asymptote condition: Identify the condition for a vertical asymptote in a rational function. A vertical asymptote occurs where the denominator of the function is equal to zero, since the function is undefined at that point. For the given function y=x+91, the denominator is x+9.
Set denominator equal to zero: Set the denominator equal to zero to find the value of x where the vertical asymptote occurs. The equation to solve is x+9=0.
Solve for x: Solve the equation x+9=0 for x by subtracting 9 from both sides. This gives x=−9.
Location of vertical asymptote: The value of x found in the previous step is the location of the vertical asymptote. Therefore, the equation of the vertical asymptote is x=−9.
