You can put this solution on YOUR website!
y=+-5x%5E2.....here you have parabola with vertex in (0,0) and a=-5 which means a%3C0 and parabola opens downward

+graph%28+600%2C+600%2C+-5%2C+5%2C+-10%2C+10%2C-5x%5E2%29+
so,
the domain is all real numbers

& range
all real numbers less and equal to zero
