Answer:
Step-by-step explanation:
A number that can be represented in p/q , where q≠ 0, is called a rational number. When divided, the result will be a whole number or in decimal form.
If it is in decimal form, decimal will either be terminated or decimal will be non terminating repeating form.
Eg; 1.2121....

The vertical asymptotes are: "x = 3" and "x = -3" .

f(x) =
;
We know that "(x² − 9) ≠ 0 ; since we cannot divide by "0" ; so the "denominator" in the fraction cannot be "0" ;
since: 9 − 9 = 0 ; "x² " cannot equal 9.
So, what values for "x" exist when "x = 9" ?
x² = 9 ;
Take the square root of EACH SIDE of the equation ; to isolate "x" on one side of the <span>equation ; and</span> to solve for "x" ;
√(x²) = √9 ;
x = ± 3

So; the vertical asymptotes are: "x = 3" and "x = -3" .
