Question
### Understanding Polynomial Graphs

#### Graph Description
The given image displays a coordinate grid with a graph of a polynomial function. The x-axis ranges from -8 to 8, and the y-axis ranges from -8 to 8. Each axis is marked with integer values. The graph resembles an upward-opening parabola, intersecting the y-axis above the x-axis and having a vertex positioned at the lowest point of the curve. 

#### Question Prompt
Below the graph, the question posed is:
"What is the least possible degree of the polynomial graphed above?"

#### Explanation
Polynomials are mathematical expressions consisting of variables and coefficients, structured as a sum of terms where each term includes the product of a coefficient and a variable raised to a non-negative integer exponent. The degree of a polynomial is determined by the highest power of the variable present in the polynomial.

In our graph, the curve is a parabolic shape, which indicates that the polynomial is a quadratic function. Quadratic functions are polynomials of degree 2 and are generally expressed in the form \( ax^2 + bx + c \). The shape of this graph (a single parabola) confirms that the least possible degree of the polynomial matching this graph is 2.

#### Answer Box
An interactive text box is provided to input the answer to the question posed about the polynomial's degree.

**Answer:** The least possible degree of the polynomial graphed above is **2**.
