Comparing Functions and Qualitative Graphs Test

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the definition of a qualitative graph?

Back

A qualitative graph represents the general behavior of a function without specific numerical values.

Front

How can you determine if a table represents a function?

Back

A table represents a function if each input (x-value) corresponds to exactly one output (y-value).

Front

What does it mean if a graph has a zero slope?

Back

A zero slope means the line is horizontal, indicating no change in the y-value as x changes.

Front

What does a positive slope indicate in a graph?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate in a graph?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is the initial value in a linear equation?

Back

The initial value is the y-intercept, which is the value of y when x is 0.

Front

How do you find the rate of change in a graph?

Back

The rate of change is found by calculating the slope of the line, which is the change in y divided by the change in x.

Front

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

Back

The y-intercept is the point where the graph crosses the y-axis, representing the output when the input is zero.

Front

What does it mean if a graph is not a function?

Back

A graph is not a function if any vertical line drawn intersects the graph at more than one point.
