What is the constant of variation for the quadratic variation? x 2 3 4 5 6 y 20 45 80 125 180 A.5 B.10 C.15 D.25

Given: x  =   2     3     4      5     6 y  = 20 ; 45 ; 80; 125;180 The constant variation for the quadratic variation is 5. y = 5x² y = 5(2²) = 5(4) = 20 y = 5(3²) = 5(9) = 45 y = 5(4²) = 5(16) = 80 y = 5(5²) = 5(25) = 125 y = 5(6²) = 5(36) = 180
