Graph Characteristics and Behaviors

The video tutorial covers six types of graphs: quadratic, linear, cubic, reciprocal, square root, and exponential. Each graph type is explained with its equation, shape, and key characteristics. Quadratic graphs have a U-shape, linear graphs are straight lines, cubic graphs have inflection points, reciprocal graphs feature asymptotes, square root graphs start at zero, and exponential graphs grow rapidly. The tutorial emphasizes understanding the behavior and properties of each graph type.

What is the general shape of a quadratic graph?

• A straight line

• A circle

• A V-shape

In the equation y = 3x - 2, what does the number 3 represent?

• The y-intercept

How does a cubic graph differ from a quadratic graph?

• It has a U-shape

What happens to the value of y in a reciprocal graph as x approaches zero?
