Question

Polynomials are everywhere. It is found in the slope of a hill, the curve of a bridge or the continuity of a mountain range.

Based on the given information, answer the following question.

If the equation of the bridge is prepersented by the following graph $y=p\left(x\right)$, then name the type of the polynomial it traces.

• A. Linear
• B. Quadratic
• C. Cubic
• D. Bi-quadratic

Answer 1

The correct option is B Quadratic


The graph here, cuts the x-axis at two different points.
Hence, the number of zeroes for the given graph is 2.

We know that, the degree of the polynomial indicates the maximum number of zeroes it can have.

Here, the maximum number of zeroes is 2.
Thus, $y=p\left(x\right)$ has to be a quadratic equation.
