Comparing Functions Flashcard 2 Review

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

When is a function's profit constant according to a graph?

Back

A function's profit is constant when the graph is horizontal over a certain interval.

Front

What does it mean when y approaches +∞ as x approaches -∞?

Back

It means that as x decreases without bound, the value of y increases without bound.

Front

How can you determine when a function is decreasing?

Back

A function is decreasing when the y-values decrease as the x-values increase.

Front

What is the significance of the y-intercept in a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, indicating the output value when x=0.

Front

What does it mean for a function to be increasing?

Back

A function is increasing when the y-values increase as the x-values increase.

Front

How do you find the maximum value of a function?

Back

The maximum value of a function can be found by identifying the highest point on the graph of the function.

Front

What is a horizontal asymptote?

Back

A horizontal asymptote is a horizontal line that the graph of a function approaches as x approaches ±∞.

Front

What is a vertical asymptote?

Back

A vertical asymptote is a vertical line that the graph of a function approaches but never touches, typically where the function is undefined.
