Polynomials in Real Life

Polynomials are everywhere. It is found in a roller coaster of an amusement park, the slope of a hill, the curve of a bridge or the continuity of a mountain range. They play a key role in the study of algebra, in analysis and on the whole many mathematical problems involving them.

Based on the given information, answer the following question:

If the path traced by the Roller Coaster is represented by the graph $y=p\left(x\right)$, find the number of zeroes?

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is D 3

We know that the number of times the graph cuts/touches the x-axis is equal to the number of zeroes.

The given graph exactly cuts the x-axis at three distinct points.

So, it will have three zeroes.

Therefore, option (d) is the correct answer.
