The video tutorial explains the Intermediate Value Theorem, emphasizing its application in finding zeros of polynomials. It describes how a continuous graph ensures that all y-values between two points are covered without lifting the pen. The tutorial further illustrates how to identify x-intercepts by observing changes in y-values from positive to negative or vice versa, using graphical representation and analysis.

What does the Intermediate Value Theorem imply about a continuous graph?

• It only covers positive Y values.

• It skips certain Y values.

• It covers all Y values between two points.

• It has breaks and gaps.

What is a characteristic of a continuous graph?

• You can draw it without lifting your pen.

• It only exists in theory.

• It has multiple breaks.

• It is always a straight line.

What does a continuous graph ensure about Y values?

• They are all zero.

• All Y values between two points are covered.

• They are all negative.

• They are all positive.

What is the role of the Intermediate Value Theorem in graph analysis?

• To calculate the area under the curve.

• To find the highest point.

• To determine the slope.

• To ensure all Y values between two points are covered.
