PLEASE HELPPP I WILL GIVE BRAINLIEST

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.

What is the best way to answer questions with a x expression in the question. for example 3x + 10x=?

What percent of 18 is 24? and plz explain thx.
