Let \(p\) be the tangent to the graph of the function \(f(x) = x^{2} - x - 6\) parallel to the line \(y = 3x + 1\). Find the point \(A\) where \(p\) touches the graph of \(f\).
\(A = \left [2;-4\right ]\)
\(A = \left [2;4\right ]\)
\(A = \left [1;6\right ]\)
\(A = \left [-1;-4\right ]\)

Let \(p\) be the tangent to the graph of the function \(f(x) = x^{2} + 4x - 2\) perpendicular to the line \(x + 6y + 2 = 0\). Find the point \(A\) where \(p\) touches the graph of the function \(f\).
\(A = \left [1;3\right ]\)
\(A = \left [-5;3\right ]\)
\(A = \left [-3;-5\right ]\)
\(A = \left [0;-2\right ]\)
