The coordinates of point a on a coordinate grid are (−2, −3). point a is reflected across the y-axis to obtain point b and across the x-axis to obtain point c. what are the coordinates of points b and c?

Consider u = {x|x is a negative real number}which is an empty set? o {x|x eu and x has a negative cube root}o {x|x eu and x has a negative square root}{x|x eu and x is equal to the product of a positive number and -1}{x|x eu and x is equal to the sum of one negative and one positive number?
