Answer:Please see the attachment for graph. Step-by-step explanation:We are a given a equation and need to graph it. It is square root function. We make table of x and y and then plot the points on graph and join the points. We will take some random values of x and then find the value of y corresponding to the value of x. For x=1, Put x=1 into equation [tex]y=-4\sqrt{1}=-4[/tex]For x=4, Put x=4 into equation [tex]y=-4\sqrt{4}=-8[/tex]For x=9, Put x=9 into equation [tex]y=-4\sqrt{9}=-12[/tex]Table of x and y x y 1 -4 4 -8 9 -12Now we plot the points on graph and join the points.
