For this case we must find the domain of the following function:


f (x) = x ^ 2 + 4x ^ 2 + 3x + 2

We add similar terms:


f (x) = 5x ^ 2 + 3x + 2

By definition, the domain of a function is given by all the values for which the function is defined. In this case, the function is defined for all real numbers.

So, the domain is given by:

(-∞,∞)

Answer:

(-∞,∞)
