Graph the equation y= 6+6x-1/3x^2

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

probably .5

i can on others if necessary.

to complete this square you have to rotate about the origin 270 degrees clockwise.

parallelogram is the   answer
