M8 Unit 5 Review (Functions)

Front

Is the relation a function?

Back

No, because the x-value 11 has two y-values pair with it.

Front

What is the range of the function with outputs {-2, -1, 0, 3}?

Back

{-2, -1, 0, 3}

Front

What is the first number in an ordered pair?

Back

The x-coordinate.

Front

Write the linear equation in y = mx + b form using the points (0, 2) and (2, 1).

Back

y = -1/2x + 2

Front

Which equation matches the table of values?

Back

y = x + 4

Front

What is a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

What does the slope (m) represent in a linear equation?

Back

The rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The value of y when x = 0.

Front

How do you determine if a relation is a function using a vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values).
