What is the general shape of a linear graph?

Back

The graph of a linear function is a straight line.

Front

What is the general shape of a quadratic graph?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards.

Front

What is the general shape of an exponential graph?

Back

The graph of an exponential function increases or decreases rapidly, forming a curve that approaches the x-axis but never touches it.

Front

How do you identify a linear function from a table of values?

Back

A linear function will have a constant rate of change (slope) between the values.

Front

How do you identify a quadratic function from a table of values?

Back

A quadratic function will show a constant second difference in the values of the output.

Front

How do you identify an exponential function from a table of values?

Back

An exponential function will show a constant ratio between consecutive output values.
