Let's analyze the problem shown in the image.

We are given the derivative of a function $f'(x) = 6\left(\frac{2}{x^2} - \sqrt{x}\right)$, and the question asks whether the function $f(x) = -\frac{12}{x} - 2\sqrt{x}$ is correct.

Step 1: Integrate $f'(x)$ to find $f(x)$

Given: $f'(x) = 6\left(\frac{2}{x^2} - \sqrt{x}\right)$

We can split this into: $f'(x) = 6 \cdot \frac{2}{x^2} - 6 \cdot \sqrt{x}$ $f'(x) = \frac{12}{x^2} - 6x^{\frac{1}{2}}$

Now, integrate each term separately.

1. Integrate $\frac{12}{x^2}$: $\int \frac{12}{x^2} \, dx = \int 12x^{-2} \, dx = 12 \cdot \left(-\frac{1}{x}\right) = -\frac{12}{x}$

2. Integrate $-6x^{\frac{1}{2}}$: $\int -6x^{\frac{1}{2}} \, dx = -6 \cdot \frac{2}{3} x^{\frac{3}{2}} = -4x^{\frac{3}{2}} = -4\sqrt{x} \cdot x$

So, after integrating, we have: $f(x) = -\frac{12}{x} - 4x^{\frac{3}{2}} + C$

Step 2: Compare with the given function

The function given is: $f(x) = -\frac{12}{x} - 2\sqrt{x}$

This does not match the function we obtained by integrating $f'(x)$, which had a term $-4\sqrt{x}$ instead of $-2\sqrt{x}$.

Conclusion:

The function $f(x) = -\frac{12}{x} - 2\sqrt{x}$ is not correct, hence the statement is False.
