Write a function rule to describe the the amount of change c(x) you get from a $20.00 bill if you buy x pounds of candy at $2.25 a pound. c(x) = 20x + 2.25 c(x) = 20x - 2.25 c(x) = 20 - 2.25x c(x) = 20 + 2.25x w

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.
