Given:
Here a graph of cos function is given in the question.
Required:
We need to find the blank boxes.
Step-by-step 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:
