How to Graph a Quadratic Equation
You graph a quadratic equation by plotting the function y = ax^2 + bx + c. Start by finding the vertex using the formula x = -b/(2a), then plot points on either side to get the parabolic shape!

Just use an online graphing calculator and plug in your equation. Saves time and effort!
First-hand advice: Make sure to calculate and plot the vertex and the points at x-intercepts (if they exist). This helps in understanding the behavior of the parabola.
Honestly, sketch the vertex, find the intercepts, and remember it's a U shape. Easy peasy.
Use the vertex form of the equation to easily find the vertex, and then draw! Don't forget to plot a few extra points for accuracy.
