Answer:
Correct answer is A.
Step-by-step explanation:
Let [tex]f(x) = \sqrt{x} -1[/tex]. By definition, the radical function of the form [tex]\sqrt{x}[/tex] has its domain in the interval [tex][0, +\infty)[/tex], and the -1 component of the sum makes an downward translation, that is, in the -y direction. We present below a figure with a comparison between [tex]g(x) = \sqrt{x}[/tex] (red line) and [tex]f(x) = \sqrt{x} -1[/tex]. (blue line)
Hence, the correct answer is A.
