Graphing Factored Quadratics Quiz

What does a positive 'a' value indicate about the graph of a quadratic equation?

• The graph has no x-intercepts.

• The graph is a sad face.

• The graph is a straight line.

• The graph is a happy face.

In a quadratic equation, what do the terms 'roots' and 'zeros' refer to?

• The axis of symmetry.

• The y-intercepts of the graph.

• The x-intercepts of the graph.

• The maximum point of the graph.

How do you write the equation of a quadratic with one zero intercept and one positive intercept?

• f(x) = a(x + 0)(x - q)

• f(x) = a(x - 0)(x - q)

• f(x) = a(x + p)(x + q)

• f(x) = a(x - p)(x + q)

What is the first step in graphing a quadratic using intercept form?

• Determine the vertex.

• Find the y-intercept.

• Calculate the slope.

• Identify the axis of symmetry.

How do you find the axis of symmetry for a quadratic equation?

• By finding the midpoint of the y-intercepts.

• By averaging the x-intercepts.

• By calculating the slope of the line.

• By finding the maximum point of the graph.

What is the domain of a standard quadratic function?

• Numbers greater than zero.

• Only negative numbers.

• Only positive numbers.

• All real numbers.

In a downward facing quadratic graph, what does the range represent?

• Values greater than the maximum.

• Values less than or equal to the maximum.

• Values greater than or equal to the minimum.

• All real numbers.

What is the vertex of a quadratic equation with x-intercepts at -3 and 1?

• (-1, 8)

• (-3, -4)

• (0, 0)

• (2, 9)

How do you determine the y-intercept of a quadratic equation in intercept form?
