**Problem Statement:**

Consider the function \( f(x) = 5x^{10} + 7x^5 - 6x^4 - 4 \).

Enter an antiderivative of \( f(x) \). Do not enter \( +c \) as part of your answer.

**Answer:** [   ] \( + c \) 

---

**Explanation:**

To find the antiderivative (or indefinite integral) of the function \( f(x) = 5x^{10} + 7x^5 - 6x^4 - 4 \), apply the power rule for integration, which states:

\[
\int x^n \, dx = \frac{x^{n+1}}{n+1} + C
\]

Apply this rule to each term in the function separately:

1. For \( 5x^{10} \):
   \[
   \int 5x^{10} \, dx = \frac{5x^{11}}{11}
   \]

2. For \( 7x^5 \):
   \[
   \int 7x^5 \, dx = \frac{7x^6}{6}
   \]

3. For \( -6x^4 \):
   \[
   \int -6x^4 \, dx = \frac{-6x^5}{5}
   \]

4. For \( -4 \):
   \[
   \int -4 \, dx = -4x
   \]

Combine the results:

\[
F(x) = \frac{5x^{11}}{11} + \frac{7x^6}{6} - \frac{6x^5}{5} - 4x + C
\]

Omit \( +C \) as instructed.
