Determine the implied domain of the given function. Express in interval notation
(4x^(2)3x)/(2)

Why can't x be any real or complex number?

THat's what the assignment says. I don't understand it

The domain of x goes from infinity to + infinity.

f(x) =  (4x^2+3x)/2 =(1/2)x(4x+3)
sketch a graph
x f(x)
oo oo
3 13.5
2 5
1 1/2
3/4 0
1/2 +.25
0 0
+1 7/2
+oo oo
it's domain is fine for all real x
On the other hand the range is limited and never gets higher than 9/32 at x = 3/8
