How to analyze a quadratic function to graph

The video reviews quadratic functions, focusing on vertex form. It covers finding the axis of symmetry, vertex, and determining if the vertex is a maximum or minimum. It also explains how to find X and Y intercepts and solve quadratic equations using factoring.

What is the formula to find the axis of symmetry in a quadratic function?

• x = -B / 2A

• x = B / 2A

• x = 2A / B

• x = A / 2B

How do you find the y-coordinate of the vertex in a quadratic function?

• By using the formula y = -B / 2A

• By setting x = 0

• By using the formula y = C

• By substituting the x-coordinate of the vertex into the function

If the value of 'a' in a quadratic function is greater than zero, what can be said about the vertex?

• It is both a maximum and a minimum

• It is neither a maximum nor a minimum

• It is a minimum point

• It is a maximum point

What is the y-intercept of a quadratic function in standard form?

• The value of x when y = 0

• The value of B

• The value of A

• The value of C

Which method can be used to find the x-intercepts of a quadratic function if it cannot be factored?

• Using the quadratic formula

• Using the axis of symmetry

• Using the zero product property

• Using the value of C
