Exponential Functions and Graphing

The video tutorial explains how to graph an exponential equation using the example Y = 8 * 2^X. It covers the basics of the coordinate plane, identifying the initial value, plotting points, and understanding the Y-intercept. The tutorial demonstrates how to graph the exponential function by connecting plotted points and discusses the behavior of exponential graphs, including their rapid increase and asymptotic approach towards the x-axis.

What is the example equation used to demonstrate graphing an exponential equation?

• Y = 10 * 2^X

• Y = 5 * 3^X

• Y = 8 * 2^X

• Y = 7 * 2^X

On a coordinate plane, which axis represents the horizontal direction?

• W-axis

• Z-axis

• Y-axis

• X-axis

What scale is used in the example to keep the graph neat?

• Scale of 10

• Scale of 5

• Scale of 2

• Scale of 1

Where is the initial point plotted on the graph for the equation Y = 8 * 2^X?

• (1, 8)

• (1, 16)

• (0, 2)

• (0, 8)

When X = 1, what is the value of Y for the equation Y = 8 * 2^X?

• 16

• 8

• 10
