Question

Find the domain of the function f(x)=x2+4x2+3x+2

Answer 1

Solution: -∞ < x < ∞

Interval Notation: (-∞ , ∞ )

Explanation

x*2+42*2+3x+2

= 5x+4 * 2x+2

= 5x+8x+2

= 13x+2

Answer 2

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:

(-∞,∞)
