Smallest Range Value
If the domain of g(x) = 1 - 5x is -3 ≤ x ≤ 2, what is the smallest range value of g(x)?

$1-5x\geq 1-5*2=-9$

It should be a straightforward business to draw the graph (a line) of y = 1 - 5x over the given domain and get the range from the y-coordinates of the endpoints. Where are you stuck?
