Answer the question in the picture above

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.

Do,h = (7, 9) (14, 18) the scale factor is

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
