Find the derivatives of the following (1-3) functions :
`f(x)=2x-3/4`

Answer

To find the derivative of the function \( f(x) = 2x - \frac{3}{4} \), we will follow the rules of differentiation step by step.

### Step 1: Identify the function
The given function is:
\[ f(x) = 2x - \frac{3}{4} \]

### Step 2: Differentiate each term
We will differentiate each term of the function separately.

1. The first term is \( 2x \).
- The derivative of \( 2x \) with respect to \( x \) is \( 2 \). This is because the derivative of \( ax \) (where \( a \) is a constant) is \( a \).

2. The second term is \( -\frac{3}{4} \).
- The derivative of a constant is \( 0 \). Therefore, the derivative of \( -\frac{3}{4} \) is \( 0 \).

### Step 3: Combine the derivatives
Now, we combine the derivatives of both terms:
\[ f'(x) = 2 + 0 = 2 \]

### Final Answer
Thus, the derivative of the function \( f(x) = 2x - \frac{3}{4} \) is:
\[ f'(x) = 2 \]
