Question

The above picture are few natural examples of parabolic shape which is represented by a quadratic polynomial. A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.

Based on the above information, answer the following questions.

In the above graph, how many zeroes are there for the polynomial $x^2-2x+3$?

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is C 2


Here, we can clearly observe that, the graph of the polynomial $x^2-2x+3$ cuts the x axis at two distinct points.
Hence the number of zeroes for the given polnomial is 2.
