Front

Which graph does NOT pass the vertical line test?

Back

Graph 1- is NOT a function.

Front

What is the end behavior of the function as x approaches -∞?

Back

f(x) approaches -∞.

Front

What is the end behavior of the function as x approaches +∞?

Back

f(x) approaches -∞.

Front

What is x if f(x) = -2?

Back

x = 8.

Front

What is the domain of the graph?

Back

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 vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph more than once, it is not a function.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as x increases, f(x) decreases.
