Here is a picture of a circle. Each square represents 1 square unit. Explain why the area of the circle is less than 4 square units.

because there isnt any full circles. in order to have a square you need 4 corners .they all only have 1 inside that circle.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
