Which graph does note represent a non-linear function

its the 3rd one

Step-by-step explanation:

a nonlinear function means that the data is not linear, to be a nonlinear function, the data has to be a funtion but it does not form a straight line.

nonlinear functions will have interesting shapes like curves or Vs

The third one

Step-by-step explanation:

All of them except the 3rd one, makes a stright line

Hope this helps!!!

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
