Combo 2 Readiness Standards up to Compound Interest

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

What does it mean for y to be a function of x?

Back

It means that for every x value, there is exactly one corresponding y value.

Front

How can you determine if a mapping represents y as a function of x?

Back

Check if any x value is associated with more than one y value; if so, it is not a function.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What is the vertical line test?

Back

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 is a table of values in relation to functions?

Back

A table of values lists pairs of x and y values, showing how y changes with x.

Front

What is a graph in mathematics?

Back

A visual representation of data or a function, showing the relationship between x and y.

Front

What does it mean if a graph does not represent y as a function of x?

Back

It means that there are x values that correspond to multiple y values.
