El dominio de una función es el conjunto de valores {1, 2, 3, 4} y el contra-dominio es el conjunto {1, 4, 9, 16}. ¿Cuál es la función que relaciona estos dos conjuntos? * 2 puntos

f(x) = x +3

f(x) = 3x

f(x) = x2

f(x) = 2x​

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.

the first one
