13.33

Step-by-step explanation:

To find this you need to find out how many KB can be downloaded in one minute. If 900KB are downloaded in 3 minutes then 300KB are downloaded in one minute. (I found this by dividing 900 by 3) To find out how many minutes it will take you will need to divide the amount downloaded in one minute from the amount of KB you need to download.

Example: 900 ÷ 3 = 300 and then 4000 ÷ 300 = 13.33.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
