Initial Value of Exponential Functions

The video tutorial explains how to determine the initial value of an exponential function using both a table of values and a graph. It describes the general form of an exponential function, y = a * B^x, where 'a' is the initial value. The tutorial demonstrates finding this initial value by identifying the y-value when x equals zero in both a table and a graph, concluding that the initial value is 10 in both cases.

What is the initial value of an exponential function when x equals 0 in a table of values?

• The value of x when y equals 1

• The value of x when y equals 0

• The value of y when x equals 0

• The value of y when x equals 1

In the given table, what is the initial value of the exponential function?

• 20

• 15

• 10

• 5

How is the initial value represented in the equation of an exponential function?

• As the variable y

• As the coefficient a

• As the exponent x

• As the base B

What is the equation form of the exponential function with an initial value of 10?

• y = x * 10^B

• y = 10 * B^x

• y = B * 10^x

• y = 10 * x^B

Where do you find the initial value of an exponential function on a graph?

• At the lowest point of the graph

• Where the graph crosses the x-axis

• At the highest point of the graph

• Where the graph crosses the y-axis

In the graph example, what is the initial value of the exponential function?

• 20

• 15

• 10

• 5
