slide3
Given the following function,

If: a > 0, then shift the graph “a” units up

If: a < 0, then shift the graph “a” units down

slide4
Given the following function,

Since a > 0, then shift the

graph “3” units up

slide12
Given the following function,

We get the expression (x - b)

and equal it to zero

x - b = 0

x = b

If: b> 0, then shift the graph

“b” units to the rightIf: b< 0, then shift the graph

“b” units to the left

slide13
Given the following function,

x – 1 = 0

x = 1

Since 1> 0, then shift

the graph “1” unit right

graphing
Graphing

Recall: Shift “3” units up since 3 > 0

then we use the expression x + 1,

and equal it to zero

x +1 = 0

x = -1

Since –1 < 0, then we shift

“1” unit to the left

slide29

Given the following function,

For this equation, c determines

how wide or thin it will be.

if: |c|>1, then the graph is closer to the y-axis

if: |c|=1, then the graph remains the same

if: 0<|c|<1, then the graph is further

from the y-axis

if c is a negative number, then the graph

will reflect on the x-axis

slide30
Given the following function,

Since |5| > 0, then the

graph is closer to the y-axis

slide40
Given the following function,

Since 4 > 0, shift the graph “4” units up

x – 1 = 0

x = 1

Since 1> 0, then shift the graph

“1” unit to the right

Since |5| > 0 shift the graph

closer to the y-axis.
