Answer:
Solution: -∞ < x < ∞
Interval Notation: (-∞ , ∞ )
Step-by-step explanation
x*2+42*2+3x+2
= 5x+4 * 2x+2
= 5x+8x+2
= 13x+2
For this case we must find the domain of the following function:
[tex]f (x) = x ^ 2 + 4x ^ 2 + 3x + 2[/tex]
We add similar terms:
[tex]f (x) = 5x ^ 2 + 3x + 2[/tex]
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:
(-∞,∞)
