Domain and Range from Graphs

Compare the red graph f\left(x\right)=\frac{1}{x}with the blue graph g\left(x\right)=\frac{-8}{x}. What is the blue graph doing?

• The graph of g is a reflection in the y-axis and lies farther from the axes. The graphs have the same asymptotes, domain, and range.

• The graph of g is a reflection in the x-axis and lie closer to the axes. The graphs have the same asymptotes, domain, and range.

• The graph of g is a reflection in the x-axis and lies farther from the axes. The graphs have the same asymptotes, domain, and range.

• The graph of g is a reflection in the y-axis and lies closer to the axes. The graphs have different asymptotes, domains, and ranges.
