( f) h(g) = x ^ 5 + x ^ 4 is this an even, odd, or neither function

To determine if the function \( f(h(g)) = x^5 + x^4 \) is even, odd, or neither, we need to analyze the function's behavior when substituting \(-x\) for \(x\).

### Definitions
1. **Even Function:** A function \(f(x)\) is even if \( f(-x) = f(x) \) for all \(x\).
2. **Odd Function:** A function \(f(x)\) is odd if \( f(-x) = -f(x) \) for all \(x\).
3. **Neither:** If a function does not satisfy either of these conditions, it is neither even nor odd.

### Given Function
The function is:
\[
f(x) = x^5 + x^4
\]

### Step-by-Step Analysis

1. **Substitute \(-x\) into the function:**
   \[
   f(-x) = (-x)^5 + (-x)^4
   \]

2. **Simplify the expression:**
   \[
   (-x)^5 = -x^5 \quad \text{(since raising to an odd power preserves the sign)}
   \]
   \[
   (-x)^4 = x^4 \quad \text{(since raising to an even power results in a positive number)}
   \]
   Therefore,
   \[
   f(-x) = -x^5 + x^4
   \]

3. **Compare \(f(-x)\) with \(f(x)\):**
   \[
   f(x) = x^5 + x^4, \quad f(-x) = -x^5 + x^4
   \]

   - \(f(-x) \neq f(x)\), so the function is **not even**.
   - \(f(-x) \neq -f(x)\) because:
     \[
     -f(x) = -(x^5 + x^4) = -x^5 - x^4
     \]
     And \(f(-x) = -x^5 + x^4\), which is different from \(-f(x)\).

### Conclusion
The function \(f(x) = x^5 + x^4\) is **neither even nor odd**.
