Explain how the following would effect the graph of  y = f(x).

1.  y = f(x) + 2
  up 2
down 2
left 2
right 2
more narrow
wider		 2.  y = f(x + 2)
up 2
down 2
left 2
right 2
more narrow
wider
3. y = f(x - 3) + 5
 up 5
down 5
right 5
left 5
up 3
down 3
left 3
right 3
more narrow
wider		 4.  y = 5f(x)
up 5
right 5
more narrow
wider
left 5
down 5
5.  y = (1/5)f(x)
up (1/5)
right (1/5)
more narrow
wider		 6. y = - f(x)
up 1
down 1
  left 1
  right 1
more narrow
wider
upside down
7. y = -7f(x + 8) - 9
 up 8
down 8
 up 9
down 9
right 8
left 8
up 7

8.  This is the graph of:
 - f(x)
| f(x) |
f(-x)
prcl1378.jpg (66573 bytes)
9.  This is the graph of:
 - f(x)
| f(x) |
f(-x)		 prcl1379.jpg (68784 bytes)
10.  This is the graph of:
 - f(x)
| f(x) |
f(-x)
   
Solve for x.
11. y = | x | + 3 ; y = -5
  - 8
2
- 2
 8
no solution		 12.  y = - | x - 3 | + 2  ;  y = 0.3
- 0.7
  0.7
  4.7
