Use the graph to find the value of the function

Step-by-step explanation:

You could do this one of 2 ways.  First is to look at the graph and locate x = 0. That is the y-axis.  ON the y axis, the cosine curve is at a y value of 1.  Second way is to go to your calculator and, in degree mode, hit cos(0) and you'll see that it is 1.

its 4 because 2 times 2 is 4, if you double the number two you get four

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
