PLEASE HELP!! What polynomial has a graph that passes through the given points? (-2, 2) (-1, -1) (1, 5) (3, 67) A. y = -x3 + 4x2 + 2x - 2 B. y = x3 + 4x2 + 2x - 2 C. y = x4 + 4x3 + 2x2 - 2x D. y = x3 - 4x2 - 2x - 2

OpenStudy (jdoe0001):

test the given choices say -2, 2 meaning x = -2 thus y = 2, or should testing the 1st one y = \((-2)^3+4(-2)^2+2(-2)-2\) is that really equals to 2? test it
