$y={-11,1,10}$

The range of a function is the list of all resultant values (often called the $y$ or $f(x)$ values) that arise from the list of domain values.

Here we have a domain of $x={-3,1,4}$ in the function $y=3x-2$ . This gives as the range:

$y=3(-3)-2=-11$
$y=3(1)-2=1$
$y=3(4)-2=10$

$y={-11,1,10}$

What is the range of the function y=3x-2y=3x-2 when the domain is {-3, 1, 4}?
