Suppose y= f(x) + k. what effect does k have on the parent function? a) shifts the function up or down b) shifts the function left or right. c) reflects the function across the x-axis d)reflects the function across the y-axis

ANSWER

A) shifts the function up or Down

EXPLANATION

The given function is



The parent function is



The given transformation is a a vertical translation that shifts f(x) up or down by k units.

If k is negative, the parent function shifts downwards by k units.

If k is positive, the parent function shifts upwards by k units.

The correct choice is

A) shifts the function up or Down
