Using the following equation, find the center and radius of the circle. you must show all work and calculations to receive credit. x2 − 4x + y2 + 8y = −4 (10 points)

The center is located at (2, −4), and the radius is 4.

Step-by-step explanation:

  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.
