Identifying Graph Models and Equations

The video tutorial explains the differences between linear, exponential, and quadratic models. It covers the equations and graph representations of each model type. The tutorial also demonstrates how to identify these models using tables and graphs, highlighting key characteristics such as straight lines, curves, and parabolas.

What is the primary characteristic of a linear model when graphed?

• It forms a zigzag pattern.

• It forms a circle.

• It forms a straight line.

• It forms a curve.

Which equation represents a linear model?

• Y = a / x

• Y = a * B^X

• y = m x + B

• Y = A X^2 + bx + C

What type of graph does an exponential model create?

• A zigzag

• A curve

• A parabola

• A straight line

Which equation is used for an exponential model?

• Y = A X^2 + bx + C

• y = m x + B

• Y = a * B^X

• Y = a / x

What shape does a quadratic model form on a graph?

• A circle

• A curve

• A parabola

• A straight line

Which equation represents a quadratic model?

• Y = A X^2 + bx + C

• y = m x + B

• Y = a / x

• Y = a * B^X

How can you identify a linear model from a table of values?

• The Y values decrease consistently.

• The Y values are added by the same amount.

• The Y values form a zigzag pattern.

• The Y values are multiplied by the same factor.

What indicates an exponential model in a table of values?

• The Y values form a straight line.

• The Y values decrease consistently.

• The Y values are multiplied by the same factor.

• The Y values are added by the same amount.

What does a curved graph that decreases from a high point to a low point represent?

• Linear decay

• Linear growth

• Exponential decay

• Quadratic growth

How can you determine if a graph represents a quadratic model?

• It forms a zigzag pattern.

• It forms a straight line.

• It forms a parabola.

• It forms a circle.
