Objective: Be able to graph quadratic functions by making a table of values. Be able to recognize
patterns in quadratic functions.
Warm-up:
1. Simplify: (𝑥 − 4)2
2. Classify by degree and number of terms: 𝑦 = 5𝑥 3 𝑦 − 2𝑥 2 𝑦 5
Degree: _____________
Number of terms: ______________
Make a table with x=-2, -1, 0, 1, 2 for each of the following and graph:
𝑦 = 𝑥2
𝑦 = −2𝑥 2
𝑦 = 2𝑥 2
𝑦 = −3𝑥 2
𝑦 = 𝑥2 + 1
𝑦 = 2𝑥 2 − 1
𝑦 = 2𝑥 2 − 4𝑥 − 5
𝑦 = 𝑥2 − 2
𝑦 = −𝑥 2 + 3
𝑦 = −𝑥 2 + 4𝑥 − 1
