Answer:
what is your question there is no equation
Answer:
4/75
Step-by-step explanation:
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
The answer is true because they both have the 90 degree box and a mark in the line indicating they are the same length.
