Final answer:
When f = 1, the value of the expression 4 - 2f is 2.
Step-by-step explanation:
To evaluate the expression 4 - 2f when f = 1, substitute the given value of f into the expression and simplify:
- Replace f with 1: 4 - 2(1)
- Simplify: 4 - 2 = 2
Therefore, when f = 1, the value of the expression 4 - 2f is 2.
