Answer:
The domain of the function is all real numbers.
Step-by-step explanation:
Domain is the set of input values.
If a quadratic function is defined as
[tex]f(x)=ax^2+bx+c[/tex]
then the domain of the function is all real number.
The given function is
[tex]f(x)=x^2+3x+5[/tex]
It is a quadratic function and the domain of a quadratic function is all real numbers because it is defined for all real values of x.
Therefore the domain of the function is all real numbers.
