LDME Module 4 Review "Functions"

Front

Is the relation below a function? {(-3, 0), (1, -2), (0, 1), (3, -5)}

Back

Yes, because the x’s do not repeat.

Front

Express the relation as a table: {(-3, 2), (-1, -3), (1, 0), (4, -2)}

Back

c

Front

For the function f(x) = x - 3, evaluate f(1).

Back

-2

Front

What is the equation that shows the relationship between x and y in the function table below?

Back

y = x + 3

Front

Express the relation as a mapping: {(-3, 2), (-1, -3), (-1, 0), (4, -2)}

Back

a

Front

Define a function in mathematical terms.

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
