The video tutorial explains how to identify exponential functions in equations, graphs, and tables. It describes the characteristics of exponential functions, such as having a variable as an exponent in equations, increasing or decreasing at an increasing or decreasing rate in graphs, and having values that multiply by a common factor in tables. The tutorial also differentiates between linear and exponential functions, providing examples and analysis for each representation.

What is a key characteristic of an exponential function in an equation?

• The equation is in the form y = mx + b.

• The function has a constant slope.

• The variable is in the exponent.

• The function decreases at a constant rate.

How does an exponential function appear on a graph?

• It decreases at a constant rate.

• It has a constant slope.

• It forms a straight line.

• It increases at an increasing rate.

In a table, how can you identify an exponential function?

• By dividing each term by a constant factor.

• By subtracting a constant value from each term.

• By multiplying each term by a constant factor.

• By adding a constant value to each term.

What does the equation s = 7D + 2 represent?

• A logarithmic function.

• An exponential function.

What indicates an exponential function in a graph?

• The graph decreases at a constant rate.

• The slope remains constant.

• The slope increases over time.

• The graph is a straight line.
