Question

How does your cosine graph change when including the d-value?

Answer 1

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

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.
