Question 116796: State the domain of the following
h(x)= 3x^2+5x-3
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! Whenever you are trying to find the domain (the spectrum of values that x can take) you
look for things such as values of x that might cause the square root of a negative number or the
values of x that might cause a division by zero. That would mean that the domain must exclude
those values of x.
.
In this problem, there are no such considerations. The graph of this function is just a parabola
and x can take any value along the entire x-axis.
.
So the answer to this problem is that the domain of x is all real numbers in the spectrum of
minus infinity (-oo) to positive infinity (+oo).
.
Hope this helps you to understand the concept of domain a little more.
