Graph each quadratic function and state its domain and range??
2006-10-09 13:11:23 · 5 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
h(x) = -3x^2
Domain = x < 0 or x > 0
Range = y < 0
for a graph, go to http://www.calculator.com/calcs/GCalc.html
type in -3(x^2), then click the enter key on the keyboard.

I can't do the graph here, but the domain is all reals and range is reals less than or equal to zero.
The graph would be an upside down quadratic curve with the point at (0,0)

Guys, can I be picky here? There's nothing in the question which implies that the domain of x has to be real. It could be imaginary or complex. If the domain of x is purely real or purely imaginary, then the range is any negative number or any positive number respectively. If x can be complex, the range is complex and infinite.

This would be difficult to graph, I'm not sure how you would because there's no y. I'm assuming that h=y
But to simplify this, you could do
hx=-3x ^2, then divide both sides by x to get
h= -3/x*x,
or
h=-3
(Not sure if I'm right. Make sure you try it yourself first before totally trusting my answer)
Good LUck!
