How do you find the x and y intercept of a quadratic

The video tutorial covers the basics of parabolas, focusing on their graphical representation and key features such as the axis of symmetry and vertex. It explains how to identify and calculate the X and Y intercepts of a quadratic equation graphically and algebraically. The tutorial also demonstrates solving quadratic equations by factoring to find intercepts.

What is the general form of a quadratic equation?

• y = ax^2 + bx + c

• y = mx + b

• y = ax + b

• y = ax^3 + bx^2 + c

What is the axis of symmetry in a parabola?

• The line that divides the parabola into two identical halves

• The highest point of the parabola

• The lowest point of the parabola

• The point where the parabola intersects the X-axis
