Question

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 1

ANSWER

A) shifts the function up or Down

EXPLANATION

The given function is

$y = f(x) + k$

The parent function is

$y = f(x)$

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
