Front

What does it mean to vertically stretch a quadratic function by a factor of 2?

Back

It means to multiply the output of the function by 2, making the graph narrower.

Front

What does it mean to vertically compress a quadratic function by a factor of 2?

Back

It means to multiply the output of the function by 1/2, making the graph wider.

Front

What is the effect of translating a quadratic function up by 4 units?

Back

The entire graph of the function moves up 4 units, adding 4 to the output.

Front

What is the effect of translating a quadratic function down by 4 units?

Back

The entire graph of the function moves down 4 units, subtracting 4 from the output.

Front

What is the effect of translating a quadratic function left by 4 units?

Back

The entire graph of the function moves left 4 units, replacing x with (x + 4).

Front

What is the effect of translating a quadratic function right by 4 units?

Back

The entire graph of the function moves right 4 units, replacing x with (x - 4).

Front

What is the domain of a quadratic function?

Back

The domain of a quadratic function is all real numbers.
