Exploring Exponential Functions in Algebra 1

This video introduces exponential functions, explaining their structure and components, such as the initial value and common ratio. It provides examples to illustrate how exponential functions work, including calculations and order of operations. The video also covers how to identify exponential functions using tables of values and how to write equations for them. Finally, it addresses solving word problems involving exponential functions, emphasizing the importance of understanding patterns of multiplication.

What is the basic form of an exponential function?

• a * b^x

• ax^2 + bx + c

• log_b(a)

• a + bx

In an exponential function, where is the variable x located?

• As a base

• As a constant

• As an exponent

• As a coefficient

What does the 'a' in an exponential function represent?

• The base of the function

• The initial value

• The variable's exponent

• The common ratio

How do you identify an exponential function from a table of values?

• By multiplying by a constant to get from one y-value to the next

• By dividing by a constant to get from one y-value to the next

• By subtracting a constant to get from one y-value to the next

• By adding a constant to get from one y-value to the next

What is the 'b' value in an exponential function?

• The initial value

• The base of the function

• The common ratio

• The variable's exponent

What role does the 'b' value play in determining the growth or decay in an exponential function?

• Neither A nor B

• If b > 1, the function shows growth

• If b < 1, the function shows decay

• Both A and B

How can you find the 'a' value when given a table of values?

• It's the y-value when x is 1

• It's the y-value when x is 0

• It's the ratio of consecutive y-values

• It's the difference between consecutive y-values

What does an inconsistent multiplication factor between y-values indicate?

• The function is exponential

• The function is not exponential

• The function is quadratic

• The function is linear

How do you calculate the population on the fifth day using an exponential function?

• Multiply the initial value by 5

• Raise the base to the power of 5 and multiply by the initial value

• Subtract the common ratio 5 times from the initial value

• Add the common ratio 5 times to the initial value

In the context of exponential functions, what does the term 'order of operations' refer to?

• Adding before multiplying

• Multiplying before adding

• Exponents before multiplication

• Subtraction before division
