Use linear algebra techniques to find the center and the radius of the circle a(x^2 + y^2) + bx + cy + d = 0 through three given points (1, 0), (−1, 2),

and (3, 1). Sketch appropriate picture.

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

combine all like terms then its just a 2 step equation
