Quadratic Functions P2

The graph of quadratic function y = ax² + bx + c is called parabola.

• TRUE

• FALSE

It has a turning point called VERTEX which is either the lowest point or the highest point of the graph.

• TRUE

• FALSE

If the value of a > 0, the parabola opens upward and has a maximum point.

• TRUE

• FALSE

If the value of a < 0, the parabola opens downward and has a maximum point.

• TRUE

• FALSE

There is a line called axis of symmetry which divides the graph into two parts such that one-half of the graph is a reflection of the other half.

• TRUE

• FALSE

The line y = h is the axis of symmetry.

• TRUE

• FALSE

The k is the minimum or maximum value of a function.

• TRUE

• FALSE

The domain of a quadratic function is NOT the set of all real numbers.

• TRUE

• FALSE

If the parabola opens upward, the range is the set of {y:y > k}.

• TRUE

• FALSE

If the parabola opens downward, the range is the set of {y:y = k}.

• TRUE

• FALSE
