Question

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

Answer 1

For this case we have a function of the form $y = f (x)$. Where:

$f (x) = x-4$

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:

$f (1) = 1-4 = -3\\f (5) = 5-4 = 1\\f (6) = 6-4 = 2$

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

Answer:

{-3,1,2}
