Answer:
to be honest i think it would be c
Step-by-step explanation:
The way you asked the question, none of those are the answer. 2.55*10-4 is 21.5, which is not one of the options you provided.
However, you may have meant 2.55*10^-4, in which case it's 0.00025
you don't show the graph, but graphing y=x^2 it is a U shaped line that starts at (0,0) and the lines go upwards on both sides of the Y axis,
This means all real numbers above 0 and 0 will solve it
so the range is y≥0
