the coordinated of the vertices of a quadrilateral are U (4, 3), E (4, -6), N (-1, 2), and F (-1, 4). Quadrilateral UENF is reflected across the y-axis to create quadrilateral U'E'N'F. What are the coordinates of the vertices of quadrilateral of U'E'N'F'?

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.
