What is the parent function of a square root function?

Back

The parent function of a square root function is f(x) = √x.

How does the graph of a constant function look?

Back

The graph of a constant function is a horizontal line at the value of the constant.

What is the general shape of the graph of a quadratic function?

Back

The graph of a quadratic function is a parabola that opens upwards if a > 0 and downwards if a < 0.

What is the vertex of a quadratic function?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on the direction the parabola opens.
