Find the zeros and y intercept of the quadratic

The video tutorial explains how to find the intercepts and zeros of a quadratic function. It begins with an introduction to the problem, followed by an explanation of parabolas and their intercepts. The tutorial then details the process of finding the Y-intercept by substituting zero for X. It continues with methods to find the X-intercepts, including factoring and using the quadratic formula. The video concludes with a summary of the concepts covered, emphasizing the relationship between X-intercepts and zeros.

What is the relationship between the X intercepts and the zeros of a function?

• X intercepts are the same as the zeros of the function.

• X intercepts are the points where the function is increasing.

• X intercepts are the points where the function is undefined.

• X intercepts are the maximum points of the function.

How do you find the Y intercept of a function?

• By setting the function to its maximum value.

• By setting X to zero.

• By setting the function to its minimum value.

• By setting the output to zero.

Which method is NOT typically used to solve for X intercepts in a quadratic equation?

• Using linear approximation

• Using the quadratic formula

• Completing the square

• Factoring

What is the first step in factoring a quadratic equation to find the X intercepts?

• Identify two numbers that multiply to the constant term and add to the linear coefficient.

• Set the quadratic equation equal to the Y intercept.

• Find the derivative of the quadratic equation.

• Convert the quadratic equation to vertex form.

What happens when you set the output of a quadratic function to zero?

• You find the axis of symmetry.

• You find the vertex of the parabola.

• You find the X intercepts.

• You find the Y intercept.
