Which of the following expressions is in simplified form? 9j - 3-j
4 w - 5
1 1/2 n + 2.9 n
-2+ 1.4 m + 0.5

4w+5

Step-by-step explanation:

because 9j-3-j can be simplified to 8j - 3

1 1/2n + 2.9n can be simplified to 4.4n

and -2 + 1.4m + 0.5 can be simplified to 1.4m -1.5

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
