If `f(x)=x^(2)-ax`, then f(a)=

Options

A. a
B. `a^(2)-a`
C. `0`
D. 1

Explanation

To solve the problem, we need to find the value of \( f(a) \) given the function \( f(x) = x^2 - ax \).

### Step-by-step Solution:

1. **Identify the function**: We have the function defined as
\[ f(x) = x^2 - ax. \]

2. **Substitute \( x \) with \( a \)**: To find \( f(a) \), we substitute \( x \) with \( a \) in the function:
\[ f(a) = a^2 - a \cdot a. \]

3. **Simplify the expression**: Now, we simplify the expression:
\[ f(a) = a^2 - a^2. \]

4. **Calculate the result**: Since \( a^2 - a^2 = 0 \), we have:
\[ f(a) = 0. \]

Thus, the final answer is:
\[ f(a) = 0. \]
