The linear function is
To perform a horizontal translation for a linear function, you have to add/subtract the constant "c" to the x-coordinate:
• If you add the constant, y=f(x+c), the resulting translation will be to the left c units.
,
• If you subtract the constant, y=f(x-c), the resulting translation will be to the right c units.
Considering what is mentioned above, to move the linear function c units to the right, the transformation rule to use is option D. y= f(x-c)
