Understanding Linear and Exponential Functions

The video tutorial explains how to determine whether a table represents a linear or exponential function by analyzing patterns in function values. It focuses on identifying repeated multiplication to confirm an exponential function and formulating its equation. The process involves recognizing the multiplier and interval, then verifying the function graphically to ensure accuracy.

What indicates that a function is linear when analyzing a table of values?

• Repeated addition in function values

• Repeated division in function values

• Repeated subtraction in function values

• Repeated multiplication in function values

How can repeated division be expressed as repeated multiplication?

• By using the reciprocal of the divisor

• By adding the divisor

• By multiplying by zero

• By subtracting the divisor

What is the reciprocal of 4?

• 1/2

• 2

• 1/4

• 4

How do you determine the multiplier in an exponential function from a table?

• By multiplying consecutive function values

• By adding consecutive function values

• By subtracting consecutive function values

• By dividing a function value by the previous function value

What is the form of an exponential function equation?

• f(x) = a / M^(x/k)

• f(x) = ax^2 + bx + c

• f(x) = a * M^(x/k)

• f(x) = a + bx

In the exponential function equation, what does 'a' represent?

• The interval of x-values

• The rate of change

• The initial or starting amount

• The slope of the function

What is the value of 'M' in the given exponential function?

• 1/4

• 1/5

• 1/3

• 1/2

What does 'k' represent in the exponential function equation?

• The x-intercept of the function

• The interval for which the multiplier gives the output

• The initial value of the function

• The slope of the function

What is the vertical intercept of the function in the given table?

• (0, 16)

• (0, 12)

• (0, 1/4)

• (0, 3)

How can you verify the correctness of an exponential function graphically?

• By checking if it passes through the origin

• By ensuring it passes through the points given by the table

• By checking if it is a straight line

• By ensuring it has a positive slope
