Module 4 NG Flashcard - OPTIONAL extra credit

Front

What are x-intercepts and y-intercepts of a function?

Back

X-intercepts are points where the graph crosses the x-axis (y=0). Y-intercepts are points where the graph crosses the y-axis (x=0).

Front

How do you find the x-intercepts of a function?

Back

Set y=0 in the function and solve for x.

Front

How do you find the y-intercepts of a function?

Back

Set x=0 in the function and solve for y.

Front

What is a function?

Back

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

Front

What is the increasing interval of a function?

Back

The range of x-values where the function's output (y-value) is increasing.

Front

How do you determine the increasing interval of a function from a graph?

Back

Look for sections of the graph where the y-values rise as x-values increase.

Front

What is a relative maximum?

Back

A point on the graph where the function value is higher than all nearby points.

Front

How can you identify a relative maximum on a graph?

Back

Look for peaks or high points in the graph.

Front

What does it mean for a function to be increasing?

Back

As x increases, the value of f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

As x increases, the value of f(x) decreases.
