To find the domain of the function, we need to consider the individual functions and their respective domains. We have: $f_1(x) = \ln(4x^2 + 11x + 6)$ $f_2(x) = \sin^{-1}(4x + 3)$ $f_3(x) = \cos^{-1}\left(\frac{10x + 6}{3}\right)$ For $f_1(x)$: $4x^2 + 11x + 6 > 0$ Factoring the quadratic expression: $(4x + 3)(x + 2) > 0$ From this inequality, we have: $x \in (-\infty, -2) \cup \left(-\frac{3}{4}, \infty\right)$ For $f_2(x)$: $-1 \le 4x + 3 \le 1$ From these inequalities, we get: $x \in \left[-1, -\frac{1}{2}\right]$ For $f_3(x)$: $-1 \le \frac{10x + 6}{3} \le 1$ From these inequalities, we get: $x \in \left[-\frac{9}{10}, -\frac{3}{10}\right]$ Now, we need to find the intersection of the domains of the three functions: $\left(-\infty, -2\right) \cup \left(-\frac{3}{4}, \infty\right) \cap \left[-1, -\frac{1}{2}\right] \cap \left[-\frac{9}{10}, -\frac{3}{10}\right]$ To find the intersection, let's analyze the intervals: The interval $(-\infty, -2) \cup \left(-\frac{3}{4}, \infty\right)$ contains all $x$ values less than $-2$ and greater than $-\frac{3}{4}$. The interval $\left[-1, -\frac{1}{2}\right]$ contains all $x$ values between $-1$ and $-\frac{1}{2}$. The interval $\left[-\frac{9}{10}, -\frac{3}{10}\right]$ contains all $x$ values between $-\frac{9}{10}$ and $-\frac{3}{10}$. Looking at the intervals, we can see that the intersection is: $x \in \left(-\frac{3}{4}, -\frac{1}{2}\right]$ Thus, the domain of the function is $(\alpha, \beta] = \left(-\frac{3}{4}, -\frac{1}{2}\right]$. Now, we need to find the value of $36|\alpha + \beta|$: $36\left|-\frac{3}{4} - \frac{1}{2}\right| = 36\left|-\frac{5}{4}\right| =45$
