Answer:

Changing value of "d" changes the vertical shift of the cosine graph.

Step-by-step explanation:

Question says to find about how does your cosine graph change when including the d-value.

General equation of cosine function can be given as:

$y=a\cdot\cos\left(bx-c)\right)+d$

In that formula, value of "d" gives vertical shift.

So changing value of "d" changes the vertical shift of the cosine graph.
