i dont understand this..please help!?

Question

ok for my hw...we have this workbook page.. and the instruction says: write an equation in function notation for each relation
the proble is that my teacher already gave me the answer ..she wants us to make the table for the equation can someone pliss help me i dont kno how to do it

1. f(x)= x -2
2.f(x)= 1-x
3.f(x)= x+6
4.f(x)= 5 - x
5.f(x)= 2x -1

PLEASE HELP!!!! =[

Answer 1

Just make two columns, with x and f(x)

For example:
x | f(x) = x - 2
0 | -2
1 | -1
2 | 0
3 | 1
4 | 2
5 | 3

You just need a few values to show the pattern.

x | f(x) = 1-x
0 | 1
1 | 0
2 | 1
3 | 2
4 | 3
5 | 4

etc.

Remember to get the value in the right column, just plug in the value in the left column into the equation. Put the result into the right column...

x = 0
f(x) = x + 6
f(0) = 0 + 6
f(0) = 6

So you would start the columns as:
x | f(x) = x + 6
0 | 6
1 | 7
etc.

I think you can take it from here...

Answer 2

For each of the equations make a column of x values and next to each one work out the function. Ex: #1):

x f(x)
-3 -5
-2 -4
-1 -3
0 -2
1 -1
2 0
3 1

Answer 3

2 points for me... nothing for you.
