Non-Linear Functions by Substitution Systems of Linear & Non-Linear Functions by Substitution Warm-up: Simplify the following: 1.) (x – 3)2 2.) 4(x + 5)2 3.) 2(x + 4)2 – 3(x + 4) – 5

Solve the system using Substitution. 1.) y = -x2 + 3x + 4 y = x2 – 2x + 1

Solve the system using Substitution. 2.) y = -x2 – 6x – 11 y = x2 – 4x + 7

Solve the system using Substitution. 3.) x = y + 6 y = x2 + 2x – 8
