Which of the statements about the graph of the function y=2 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.
