Front

What is a function?

Back

A function is a relation where each input (x value) has exactly one output (y value).

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What does the notation c(m) = 1.45m + 3.50 represent?

Back

This notation represents a linear function where c(m) is the cost of a taxi ride for m miles.

Front

What does c(7) represent in the function c(m) = 1.45m + 3.50?

Back

c(7) represents the cost to ride 7 miles in the taxi.

Front

What is the independent variable in a function?

Back

The independent variable is the input of the function, typically represented on the x-axis.

Front

What is the dependent variable in a function?

Back

The dependent variable is the output of the function, typically represented on the y-axis.

Front

If a graph has two y-values for one x-value, is it a function?

Back

No, if a graph has two y-values for one x-value, it does not represent a function.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

Front

What does it mean if a graph passes the vertical line test?

Back

If a graph passes the vertical line test, it means that for every x-value, there is only one corresponding y-value, confirming it is a function.

Front

What is the x-axis in a graph?

Back

The x-axis is the horizontal axis in a graph, typically representing the independent variable.
