Find the general solution of the given differential equation.(x2 − 9)dydx + 6y = (x + 3)2 give the largest interval over which the general solution is defined. (think about the implications of any singular points. enter your answer using interval notation.)

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.
