Answer:
The domain of the function is
Step-by-step explanation:
Consider the provided rational function.
We need to determine the domain of the rational function.
Domain of a rational function is all real numbers except those for which the denominator is 0.
The denominator of the rational function is
From the above definition we know that:
That means for x=-3 the denominator is 0. Therefore, the domain of the function is all real number except -3.
Thus, the domain of the function is
X² + 25 = x²- (-25)
The square root of -25 is imaginary, so this is factored using complex numbers as
(x -5i)*(x +5i)
