Answer 4

to get a table, you just plug in various values of x to get corresponding values of y

Answer 5

so when x = 0

you plug it into f(x) = 1.5x - 3 to get f(x) = -3

so x = 0 and y = -3

Answer 6

one row in your table for #12 is

0 -3

Answer 7

okay then what do we do to get more on the table

Answer 8

plug in x = 1 to get f(x) = ???

Answer 9

x=1 y=-1.5

Answer 10

good, you keep doing that until you have a table big enough

Answer 11

and do i do 13 like that too ?

Answer 12

Answer 15

ok post what you got again

Answer 16

f(x)=4??

Answer 17

how did you get 4

Answer 18

i put 0 for x ???

Answer 19

ok great, you should say

when x = 0, f(x) = 4

Answer 20

so one row in your table for #13 is

0 4

Answer 21

okay then do it how we did the other one right

Answer 22

yes plug in other various values of x to get corresponding values for y
