Question

if y=f(x) then y=f(x)+k causes the graph to move k units down.
true of false?

Answer 1

It causes a vertical shift, either up or down, depending whether k is positive or negative.

Answer 2

so k would move up..? so false?

Answer 3

In the problem, it doesnt state what kind of number k is. It could move it down if k < 0, it would move it up if k > 0. So this is a very poorly worded question and should be tossed.

Answer 4

oh okayy, thank you!
