Analyzing the graph you provided, we can determine the degree and leading coefficient of the function $f(x)$.

Here’s the reasoning:

1. Degree: The graph has a parabolic shape, opening upwards in a "U" shape. This shape indicates an even degree for the polynomial because the ends of the graph point in the same direction (both going up as $x \to \infty$ and $x \to -\infty$).

2. Leading Coefficient: Since the graph opens upwards, the leading coefficient is positive. A negative leading coefficient would cause the graph to open downwards.

Based on these observations, the most accurate statement is:

The polynomial has even degree and positive leading coefficient.

Here are some related questions to deepen your understanding:

1. How can we determine the exact degree of a polynomial if given more information?
2. What characteristics of a graph indicate an odd degree?
3. How does the leading coefficient test help in sketching polynomial graphs?
4. Can a polynomial of even degree have roots or x-intercepts?
5. How would the graph look if the leading coefficient were negative?

Tip: For polynomials, even-degree functions with a positive leading coefficient open upwards, while those with a negative leading coefficient open downwards.
