Find the domain of the relation:
{(-3, -4), (-1, 2), (0, 0), (1, 3), (5, 4)}
a. {-4, 2, 3, 4}
b. {-3,-1, 0, 1, 5}
c. {-4, -3, -1,0, 1, 2, 3, 4, 5}
d. {-4, 0, 2, 3, 4}

Step-by-step explanation:

Domain is the X-value (left side number of the parenthesis),

B. {-3, -1, 0, 1, 5}

keep in mind two of the same numbers in domain cannot repeat.

we need more info to solve this

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
