Which of the statements about the graph of the function y = 2x are true? Check all of the boxes that apply.

For y = 2^x, any real number can be used as the exponent, so the domain is all real numbers. Increasing x by 1 multiplies the output by 2, and at x = 0 the output is 2^0 = 1, giving the y-intercept (0, 1). Powers of 2 are always positive, so the graph stays above the x-axis; the range is positive real numbers, not all real numbers, making statement E false.
