Please help me find DOMAIN/RANGE and the EQATION

Answer:
domain:
[tex]( - \infty , \infty )[/tex]
range:
[tex]( - \infty ,4][/tex]
equation:
[tex]y = - 2(x - 3) {}^{2} + 4[/tex]
Step-by-step explanation:
domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.
