Final answer:
The function f(m - 3) is equivalent to 17 - m.
Step-by-step explanation:
To find the value of f(m - 3), we need to substitute the expression m - 3 into the function f(x) = 14 - x. So, f(m - 3) = 14 - (m - 3). Using the distributive property, f(m - 3) = 14 - m + 3. Simplifying this expression, we get f(m - 3) = 17 - m.
Therefore, the equivalent expression to f(m - 3) is 17 - m. So, the correct option is 3) 17 - m.
