Determine the range of the function f (x) = x-4 when the domain is (1,5,6

For this case we have a function of the form . Where:

By definition, the domain of a function is represented by the set of values of the independent variable, x, for which the value of the variable y can be calculated.

For its part, the range is represented by the values of "and".

So:

Thus, the range is {-3,1,2}

{-3,1,2}

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
