**Answer: (D)**

A quadratic polynomial is a polynomial of degree two, i.e., the highest exponent of the variable is two. In general, a quadratic polynomial will be of the form: p(x): ax2 + bx + c, a≠0

## Graph of quadriatric polynomial

he graph of a quadratic polynomial is a parabola. The roots of a quadratic equation are the points where the parabola cuts the x-axis i.e. the points where the value of the quadratic polynomial is zero.

**The standard form of a parabola is**

**f(x) = ax2 + bx + c**

Which is a curve with the equation

f(x) = ax2 + bx + c

We must first find the vertex for the given equation before drawing a parabola graph.

x = -b/2a and y = f(-b/2a) can be used to accomplish this.

Plotting the graph, when the quadratic equation is given in the form of f(x) = a(x-h)2 + k, where (h,k) is the vertex of the parabola, is its vertex form.
