Key Features of Functions

Front

What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, meaning the value of y is 0.

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 does it mean for a graph to have a minimum?

Back

A minimum is the lowest point on the graph, indicating the smallest value of the function.

Front

What does it mean if a graph is increasing?

Back

A graph is increasing if, as x-values increase, the corresponding y-values also increase.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the value of x is 0.

Front

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

Back

To find the x-intercept, set y = 0 and solve for x.

Front

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

Back

To find the y-intercept, set x = 0 and solve for y.

Front

What does it mean for a graph to be decreasing?

Back

A graph is decreasing if, as x-values increase, the corresponding y-values decrease.

Front

What is a function?

Back

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

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.
