Absolutely! Here's how to find f(3):
**1. Understand f(x)**
The function f(x) is defined as f(x) = 2x - 1. This means to find the output value, you multiply the input value (x) by 2 and then subtract 1.
**2. Substitute x with 3**
We want to find f(3), so we'll replace 'x' with '3' in the function:
f(3) = (2 * 3) - 1
**3. Calculate**
Simplify the expression:
f(3) = 6 - 1
f(3) = 5
**Answer:**
f(3) = 5
