The video tutorial explores graphing techniques using the equation y = x^3. It emphasizes the importance of understanding graphs both through technology and mental computation. The tutorial covers plotting points, understanding symmetry, and using Desmos to visualize transformations. It highlights the differences between y = x^2 and y = x^3, focusing on rotational symmetry and transformations using sliders in Desmos.

Why is it important to understand graph concepts without relying solely on technology?

• To avoid using computers altogether.

• Because technology is too expensive.

• To develop a deeper understanding of the concepts.

• Because technology is unreliable.

What is the value of y when x is 1 in the equation y = x^3?
