Which expression is equivalent to this expression? 4a + (–6b) – 3a + 2b A. a + 4b B. a – 4b C. 7a – 8b D. 7a – 4b Please Help! :(

b. a-4b

Step-by-step explanation:

4a-3a=a

(-6b)+2b=-4b

combine these two and you get a-4b

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
