Answer: The vertical asymptoms are " x = 3" and " x = -3 " . __________________________________________________ The answer is: " x = ± 3 " . __________________________________________________
Explanation: ________________________________________________________ The "denominator" cannot equal "0" ; since one cannot "divide by "0" ;
So; set the "denominator" equal to "0" ; ________________________________________________________
→ " x² − 9 = 0 " ; Solve for all values of "x" ;
Add "9" to each side of the equation:
→ x² − 9 + 9 = 0 + 9 ;
to get:
→ x² = 9 ;
Take the square root of each side of the equation; to isolate "x" on one side of the equation; & to solve for "x" ;
→ √(x²) = √9 ;
→ |x| = 3 ;
→ x = ± 3 . __________________________________________________ Answer: The vertical asymptoms are " x = 3" and " x = -3 " . __________________________________________________ The answer is: " x = ± 3 " . __________________________________________________
