If A= (7, -6, 2)(6,-5,-7) (2,-8 ,8)and B= (-8, -7, 5)(-1, -9, 7)(5, 9, -4) find A+B

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
