Let J5 = {0, 1, 2, 3, 4}, and define functions h : J5 J5 and k : J5 J5 as follows: For

Chapter 7, Problem 14

(choose chapter or problem)

Let \(J_{5}=\{0,1,2,3,4\}\), and define functions h : \(J_{5} \rightarrow J_{5}) and k : \(J_{5} \rightarrow J_{5}\) as follows: For each \(x \in J_{5}\),

\(h(x)=(x+3)^{3}\) mod5 and \(k(x)=\left(x^{3}+4 x^{2}+2 x+2\right)\) mod 5.

Is h = k? Explain.

Text Transcription:

J_5 ={0,1,2,3,4}

J_5 rightarrow J_5

J_5 rightarrow J_5

x in J_5

h(x)=(x+3)^3

k(x)=(x^3 +4x^2 +2x+2)
