Use the order of operations to find the value of the expression: 20 - 12 + 8 x 5 80
16
5
48

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

27 +27 or 27times 2=54

the diffrence is 0
