Function h(x) = p(x)•q(x)•r(x). which functions could be p(x), q(x), and r(x)?  p(x) = x + 2; q(x) = −x + 1; r(x) = −5x − 1 p(x) = x − 2; q(x) = x + 1; r(x) = 5x + 1 p(x) = 4x − 2; q(x) = −3x + 1; r(x) = −x − 2 p(x) = 4x + 2; q(x) = 3x − 1; r(x) = x + 2) = −x + 1; r(x) = −5x − 1 p(x) = x − 2; q(x) = x + 1; r(x) = 5x + 1 p(x) = 4x − 2; q(x) = −3x + 1; r(x) = −x − 2 p(x) = 4x + 2; q(x) = 3x − 1; r(x) = x + 2
