The Deep Dive
To find \( h \circ g \circ f(x) \), we need to substitute the functions step by step. 1. **First, calculate \( f(x) \):** \[ f(x) = x^2 - 3x \] 2. **Next, substitute \( f(x) \) into \( g(x) \):** \[ g(f(x)) = g(x^2 - 3x) = \frac{1}{2(x^2 - 3x) - 1} = \frac{1}{2x^2 - 6x - 1} \] 3. **Finally, substitute \( g(f(x)) \) into \( h(x) \):** \[ h(g(f(x))) = h\left(\frac{1}{2x^2 - 6x - 1}\right) = \sqrt{2\left(\frac{1}{2x^2 - 6x - 1}\right) - 1} \] Simplifying this leads to: \[ h(g(f(x))) = \sqrt{\frac{2}{2x^2 - 6x - 1} - 1} = \sqrt{\frac{2 - (2x^2 - 6x - 1)}{2x^2 - 6x - 1}} = \sqrt{\frac{7 - 2x^2 + 6x}{2x^2 - 6x - 1}} \] So, the final answer is: \[ h \circ g \circ f(x) = \sqrt{\frac{7 - 2x^2 + 6x}{2x^2 - 6x - 1}} \]
