Question

According to the graph of H(w) below, the w-axis is also the what for H(w)

Answer 1

It's the Horizontal asymptote

Answer 2

the complete question in the attached figure

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form

$y*x=k \\ y=\frac{k}{x}$

in this problem

we have

$H*W=20*5\\ H*W=100\\ H=100/W$

So

the w-axis is a horizontal asymptote

the H-axis is a vertical asymptote

therefore

the answer is the option

D. horizontal asymptote
