Given:
The function is:

To find:
The domain of the given function.
Solution:
Domain is the set of input values.
We have,

It is a quadratic polynomial.
We know that a quadratic polynomial is defined for all real values of x. So, the given function is defined for all real values of x and the domain of the given function is:
Domain = Set of all real number
Domain = (-∞,∞)
Therefore, the correct option is B.
Answer: A and c
Step-by-step explanation: because they are the only ones that have p,x,m and not just seperate.
** x + 5 = 7
x = 2
** x + 5 = 9
x = 4
{2,4}
Depending on the answer of the problem if it’s negat the sign is so on and so fourth
