part a: the area of a square is (16x2 − 8x + 1) square units. determine the length of each side of the square by factoring the area expression completely.
part b: the area of a rectangle is (81x2 − 4y2) square units. determine the dimensions of the rectangle by factoring the area expression completely. yo

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.
