<pre>

The domain is this GIVEN interval  -5 <= x <= 7  from -5 to 7, inclusive.


In the interval form, it is the set [-5,7].


The function f(x) = 2x is a linear function, monotonically increasing.


Therefore, its range is the interval between f(-5) = 2*(-5) = -10 and f(7) = 2*7 = 14.


<U>ANSWER</U>.  The domain is the interval [-5,7].  The range is the interval [-10,14].
