The video tutorial explains how to determine if a function is linear or exponential by analyzing a table of values. It demonstrates how to derive the equation of a linear function in the form f(x) = mx + b, where m is the slope and b is the y-intercept. The tutorial includes calculating the slope using ordered pairs and verifying the function graphically to ensure accuracy.

What is the main difference between a linear and an exponential function?

• Linear functions have a pattern of repeated multiplication, while exponential functions have a pattern of repeated addition.

• Linear functions have a pattern of repeated addition, while exponential functions have a pattern of repeated multiplication.

• Linear functions are always increasing, while exponential functions can decrease.

• Linear functions have a constant rate of change, while exponential functions have a variable rate of change.

What is the form of a linear function equation?

• f(x) = x^2 + bx + c

• f(x) = a^x

• f(x) = mx + b

• f(x) = ax^2 + bx + c

How do you determine the vertical intercept 'b' from the table?

• By subtracting the first x-value from the first y-value.

• By finding the last function value in the table.

• By calculating the average of all function values.

• By finding the first function value when x is zero.

What is the formula for calculating the slope 'm'?

• m = (x2 - x1) / (y2 - y1)

• m = (y2 - y1) / (x2 - x1)

• m = (y1 - y2) / (x1 - x2)

• m = (x1 - x2) / (y1 - y2)
