$$Question: Find the cubic polynomial $$f(x)$$ such that $f(0) = 4$, $f(1) = 7$, $f(2) = 22$, and $f(3) = 67$$. Why this cubic polynomial is quietly gaining attention online—especially in math education and data modeling circles—rests in its elegant fit to real-world growth patterns. While simple in setup, this problem exemplifies how cubic functions model complex trends, from economic growth to population shifts, making it a compelling example for students, educators, and professionals seeking precise yet flexible representations. Its predictable yet non-linear progression illustrates why cubic polynomials remain essential in fields like finance, engineering, and computer science. Users are drawn to understanding not just the formula, but how it reflects dynamic change in measurable systems. This question is trending in US-focused educational digital spaces as learners and professionals increasingly seek clear, accurate math frameworks adaptable to practical scenarios. No creative embellishment distorts the math—only clarity. The precise conditions—especially $f(0) = 4$ as the baseline—anchor the solution in concrete value, ensuring relevance and utility. For mobile readers exploring concepts on-the-go, short, digestible explanations paired with structural transparency enhance comprehension and dwell time. To solve for the cubic polynomial $f(x) = ax^3 + bx^2 + cx + d$, we begin by applying the known conditions. With $f(0) = 4$, we immediately identify $d = 4$. The remaining values yield a matrix system or direct substitution model. Using $f(1) = 7$, we form $a + b + c + d = 7$; $f(2) = 22$ gives $8a + 4b + 2c + d = 22$; and $f(3) = 67$ results in $27a + 9b + 3c + d = 67$. Substituting $d = 4$ simplifies equations to a system in $a$, $b$, $c$.
