Given:

Here a graph of cos function is given in the question.

Required:

We need to find the blank boxes.

Explanation:

First of all start with amplitude of graph

so here the height of graph is 1 so amplitude is 1

now to find the last box we need middle line of graph which is 0

now to find the coefficient x in terms of pi

for this the period of graph is 2

here the period of cosx is 2*pi and here also period is 2 so in the box of coefficient we put pi

now out final equation is

Final answer:

[tex]\begin{gathered} y=1\cos\pi x+0 \\ y=\cos\pi x \end{gathered}[/tex]
