question

What kind of transformation converts the graph of

(

)

–

into the graph of

(

)

–

translation 8 units right

translation 8 units left

translation 8 units up

translation 8 units down

key idea

Transformation of f ( x )	Transformation of graph of f ( x )
f ( x + h )	Translate h units left
f ( x – h )	Translate h units right
f ( x ) + k	Translate k units up
f ( x ) – k	Translate k units down

The slope-intercept form of a linear function is
