See explanantion

Explanation:

color(blue)(1->)1The general shape of the graph y=x^2 y=x2 is that of uu

color(blue)(2->)2The -4 lowers the graph of y=x^2y=x2 by 4

color(blue)(3->)3Putting a minus sign in front of the x^2x2 so that we have y=-x^2-4y=x24 turns the whole thing upside. Now we have the general shape nn

color(blue)(4->)4the 1/313 in y=-1/3x-4y=13x4 has the effect of widening the graph
