Question

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 above graph $y=p\left(x\right)$ , find its zeroes?

• A. -1, 1, 4
• B. -2, -1, 2
  
• C. -1, 1, 2
• D. -2, 1, 4

Answer 1

The correct option is A

-1, 1, 4

We know that the points where the graph $y=p\left(x\right)$ cuts/touches the x-axis are known as the zeroes of the polynomial.

The given graph exactly cuts the x-axis at -1, 1, and 4.

Therefore, option (a) is the correct answer.
