Question 696334: Please help me solve and graph the quadratic function: h(x)=-3x^2, I also need to know what the domain and range are for the graph and write them in interval notation. Please show me all steps and I must have at least five points for the equation to graph. Any help would be greatly appreciated.
Thanks,
Tina

------
If x = -2, h = -3*4= -12
If x = -1, h = -3*1 = -3
If x = 0 , h = -3*0 = 0
If x = 1 , h = -3*1 = -3
If x = 2 , h = -3*4 = -12
