Q. Find all vertical asymptotes of the following function.f(x)=x2−162x+10
Identify Vertical Asymptotes: To find the vertical asymptotes of the function, we need to determine where the denominator is equal to 0, because vertical asymptotes occur at values of x that make the denominator undefined.
Set Denominator Equal to Zero: Set the denominator equal to zero and solve for x: x2−16=0.
Find Values of x: Find the values of x that make the equation true: x−4=0 or x+4=0.
Solve Equations for x: Solve each equation for x: x=4 and x=−4.
Check Numerator for Zero: Check if these values of x also make the numerator zero, because if they do, they might be holes instead of vertical asymptotes. The numerator is 2x+10, so we plug in x=4 and x=−4 to see if it equals zero.
Numerator for x=4: For x=4, the numerator is 2(4)+10=8+10=18, which is not equal to zero.
Numerator for x=−4: For x=−4, the numerator is 2(−4)+10=−8+10=2, which is also not equal to zero.
Confirm Vertical Asymptotes: Since neither x=4 nor x=−4 make the numerator zero, they are indeed vertical asymptotes of the function f(x).
