1. **State the problem:** We are given two definite integrals:
$$\int_{-1}^4 f(x) \, dx = -2$$
and
$$\int_{-1}^4 g(x) \, dx = 9$$
We need to find the value of:
$$\int_{-1}^4 (f(x) - 4g(x)) \, dx$$
rounded to the nearest integer.
2. **Recall the properties of definite integrals:**
The integral of a sum/difference is the sum/difference of the integrals:
$$\int_a^b [f(x) \pm g(x)] \, dx = \int_a^b f(x) \, dx \pm \int_a^b g(x) \, dx$$
Also, constants can be factored out:
$$\int_a^b c \cdot g(x) \, dx = c \int_a^b g(x) \, dx$$
3. **Apply these properties:**
$$\int_{-1}^4 (f(x) - 4g(x)) \, dx = \int_{-1}^4 f(x) \, dx - 4 \int_{-1}^4 g(x) \, dx$$
4. **Substitute the given values:**
$$= -2 - 4 \times 9$$
5. **Calculate:**
$$= -2 - 36 = -38$$
6. **Final answer:**
The value of the integral is **-38** (already an integer, so no rounding needed).
