The graph of a quadratic function is a parabola. i.e., it opens up or down in the U-shape. Here are the steps for graphing a quadratic function.Step - 1: Find the vertex. Step - 2: Compute a quadratic function table with two columns x and y with 5 rows (we can take more ...
Example 1: Using a Table of Values to Graph Quadratic Functions Notice that after graphing the function, you can identify the vertex as (3,-4) and the zeros as (1,0) and (5,0). So, it's pretty easy to graph a quadratic function using a table of values, right? It's just a ma...

A parabola is the graph of a quadratic function y = ax2+ bx + c. We obtain the quadratic equation of best fit by using quadratic regression (STAT/CALC/5:QuadReg/VARS/Y-VARS/1:Function/1;Y1/ENTER). Note that r2 = .997 here, so we expect a very good fit: y = .402x2− ...
