Y=-x^2-5x+12 quadratic formula-General form of a circle The equation of a circle in general form is, x 2 y 2 Dx Ey F = 0 where D, E, and F are real numbers To more easily identify the center and radius of a circle given in general form, we can convert the equation to standard form x2 −2xy y2 The factors of x2 = (x)(x) The factors of y2 = (y)(y) Since the second sign is positive we are adding the factors meaning the signs of the factors need to be the same

(x−a) 2 (y−b) 2 = r 2 The answer is to Complete the Square (read about that) twice once for x and onceSuppose the curves are x = y 2 and x = 4 y 2 and and you want to find points on the two curves with the same yvalue Then substitute y 2 from the first equation into the second to obtain x = 4 x So to achieve the same yvalue the xvalue on the second curve must be (minus) 4 times the xvalue on the first curve x = 4y 2 and x = y 2 I hope this helps, Penny # A formula y ~ x # A converted formula y = a_1 a_2 * x This is an example of a simple conversion y ~ x gets translated into y = a_1 a_2 * x To see and understand what R actually happens, you can use the model_matrix() function This function creates a design or model matrix by, for example, expanding factors to a set of dummy variables, depending on the
