First, note that

is always positive (except for x=0), so

must be always negative.
Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.
Now,

and

are only defined for x≥0, because only for these x'es we can take the square root.
Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.
Answer: first graph
Hello There!
145 is 23.39% of 620
<u><em>HOW TO SOLVE</em></u>
<u><em></em></u>
<u><em>Equation: Y = P% * X</em></u>
<u><em>We need to solve our equation for "P"</em></u>
<u><em>P% = Y/X</em></u>
<u><em>P% = 145/620</em></u>
<u><em>p = 0.2339</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>Convert decimal to percent:</em></u>
<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>
