Verified step by step guidance1
Identify the vertical asymptotes of the function by setting the denominator equal to zero: \(x^2 - x - 12 = 0\).
Factor the quadratic equation in the denominator: \(x^2 - x - 12 = (x - 4)(x + 3)\).
Set each factor equal to zero to find the values of \(x\) that make the denominator zero: \(x - 4 = 0\) and \(x + 3 = 0\).
Solve these equations to find the vertical asymptotes: \(x = 4\) and \(x = -3\).
Compare the vertical asymptotes \(x = 4\) and \(x = -3\) with the graphs provided to determine which graph has these asymptotes.
