What is the domain of (f*g) (x)=45x^2+19x42?
Can someone please help me? I can not, for the life of me, get this. I need it explained to me in a way I won't forget.

Best ResponseYou've already chosen the best response.0Yes...domain is the X value and it goes from left to right

Best ResponseYou've already chosen the best response.1right This function is a parabola which opens upwards and looks a bit like dw:1442166537213:dw

Best ResponseYou've already chosen the best response.1excuse the rough drawing but it should give you an idea what the domain is.

Best ResponseYou've already chosen the best response.0I need to put the domain in a form like this: dw:1442166761514:dw but I don't know how to...

Best ResponseYou've already chosen the best response.1well the domain is all real numbers and you can write it as (infinity, + infinity)

Best ResponseYou've already chosen the best response.1no its all reals think about it you can any number you like into the function and it will give you a value

Best ResponseYou've already chosen the best response.0the domain depends on the domains of f and g seperately, not combined.

Best ResponseYou've already chosen the best response.0well the original term is f(x)=4x+9 and g(x)=7x3

Best ResponseYou've already chosen the best response.0spose for instance f = (x3)(x2)(x1) g = 1/(x1) (f*g) = (x3)(x2) .. but the domain is still restricted by g

Best ResponseYou've already chosen the best response.0then there is no issue concerning f*g

Best ResponseYou've already chosen the best response.0f can use all real values as inputs g can use all real values as inputs so the domain of (f*g) in this case has no restrictions to it ...
