a)


b)
Since we can't divide by zero, we need to find when:

But before, we can factor the numerator and the denominator:

Now, we can conclude that the vertical asymptotes are located at:

so, for x = -3:


For x = 4:

(6y - 11)(6y + 11) = ay
² - b |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b |add b to both sides
ay² = 36y² - 121 + b |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
