For the graph below, what should the domain be so that the function is at least 600? graph of y equals minus 2 times the square of x plus 40 times x plus 600 0 ≤ x ≤ 20 −10 ≤ x ≤ 30 x ≥ 0 All real numbers

    So your equation is \[y=-2x^2+40x+600\] the domain for polynomials is all real numbers, but your graph is asking about |dw:1438956884453:dw| domain focuses on the x values.
