For the graph below, what should the domain be so that the function is at least 300? graph of y equals minus 2 times the square of x plus 50 times x plus 300

x ≥ 0

−5 ≤ x ≤ 30

0 ≤ x ≤ 25

All real numbers

to complete this square you have to rotate about the origin 270 degrees clockwise.

i believe a. 12x≥120 is the answer

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
