draw the line of the function with its given domain. Then determine the range using interval notation:

Question

h(x)=0.5x-1 with domain (-∞,4).

Thank you...(can you explain it to me)

Answer 1

clearly the graph is just a straight line, so
just check h(x) at the endpoints of the domain.
h(-∞) = -∞
h(4) = 1
so the range is (-∞,1)
