Find all solutions of the polynomial congruence
x²+4x+1 = 0 (mod 143).
(The solutions of the congruence x² + 4x+1=0 (mod 11) are x = 3,4 (mod 11) and the
solutions of the congruence x² +4x+1 = 0 (mod 13) are x = 2,7 (mod 13).)
Determine whether each function is an injection and determine whether each is a surjection.The notation Z_(n) refers to the set {0,1,2,...,n-1}. For example, Z_(4)={0,1,2,3}. f: Z_(6) -> Z_(6) defined by f(x)=x^(2)+4(mod6). g: Z_(5) -> Z_(5) defined by g(x)=x^(2)-11(mod5). h: Z*Z -> Z defined by h(x,y)=x+2y. j: R-{3} -> R defined by j(x)=(4x)/(x-3).
Determine whether each function is an injection and determine whether each is a surjection.
