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

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

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

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

5. Classwork
Solve the following systems using Substitution in your notebook:

6. Homework 1.) y = x2 + 2x + 1 3.) y = -2x2 + x + 1 y = 2x2 + 4x – 7
Solve the following systems using Substitution in your notebook:
1.) y = x2 + 2x + 1
3.) y = -2x2 + x + 1
y = 2x2 + 4x – 7
y = 2x2 – 3x + 2
2.) y = -x2 + 6x – 10
4.) y = x2 + 3x – 10
y = x2 – 8x + 17
x = y + 7
