For each of the following functions, evaluate the derivative at the indicated value (s) :
`f(x)=x,x=1`

Answer

To evaluate the derivative of the function \( f(x) = x \) at the point \( x = 1 \), we follow these steps:

### Step 1: Identify the function
We have the function:
\[ f(x) = x \]

### Step 2: Differentiate the function
To find the derivative of \( f(x) \) with respect to \( x \), we apply the basic differentiation rule. The derivative of \( x \) is:
\[ f'(x) = \frac{d}{dx}(x) = 1 \]

### Step 3: Evaluate the derivative at \( x = 1 \)
Now, we need to evaluate the derivative at the point \( x = 1 \):
\[ f'(1) = 1 \]

### Final Answer
Thus, the derivative of the function \( f(x) = x \) at \( x = 1 \) is:
\[ \boxed{1} \]
