Let f(x)=[x-3]then f(-5/4) is A)-4 B)-5 C)-6 D)-4.25?

To find f(-5/4), we substitute -5/4 into the function f(x):

f(-5/4) = [-5/4 - 3]

Simplifying the expression inside the brackets:

f(-5/4) = [-17/4]

Therefore, f(-5/4) is equal to -17/4.

None of the given answer choices match -17/4, so the correct answer is not provided.
