Question

What restrictions are there on the range of the function H(w) below?

A. H(w) 1

B. H(w) < 0

C. H(w) > 0

D. H(w) = 1

Answer 1

H(w) > 0

Explanation:

hope this helps :)))

Answer 2

The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant. As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.

Then, the function is defined only for positive values of w and H(w) is always positive.

Then, the answer is H(w) > 0, this is the option C.
