What is a function?

Back

A function is a relation between a set of inputs (domain) and a set of possible outputs (range) where each input is related to exactly one output.

Front

Why does the data in the table NOT represent a function?

Back

The domain element 1 has two different range elements.

Front

How do you solve the equation 4(x+3)-5=2x+8?

Back

The solution is x = 0.5 or 1/2.

Front

Which point is NOT part of the solution set: (0, 0), (-10, -10), (-1, 5), (5, 20)?

Back

(-10, -10) is NOT part of the solution set.

Front

How do you find the mean of a data set?

Back

Divide the sum of all values in a data set by the number of values.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values.

Front

What number was left out of the stem-and-leaf plot for the data: 32, 38, 40, 44, 46, 47, 49, 53, 55, 58, 62, 65, 68, 70, 72, 81?

Back

The number 47 was left out of the stem-and-leaf plot.

Front

What is the domain of a function?

Back

The domain of a function is the complete set of possible values of the independent variable.

Front

What is the range of a function?

Back

The range of a function is the complete set of possible values of the dependent variable.

Front

What does it mean for two different domain elements to have the same range?

Back

It means that multiple inputs can produce the same output, which is acceptable in functions.
