If D=3x^{2}-7xD=3x 2 −7x and C=3x-2,C=3x−2, find an expression that equals D-3CD−3C in standard form.

Me i need ! find the asymptote and determine the end behavior of the function from the graph. the asymptote of the function is= blank 1 . for very high x-values,y =blank 2 options for blank 1 x=2 x=-2 x=3 x=-3 blank 2 options moves towards negative infinity moves toward the horizontal asymptote moves toward the vertical asymptote moves toward positive infinity
