How long is 12 ft in a yard

I think that 12 feet is equal to 4 yards

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

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
