Have you ever noticed how seemingly simple math problems now spark widespread interest across digital platforms? A quiet but growing curiosity surrounds a specific quadratic polynomial defined by values at three points: $ p(1) = 3 $, $ p(2) = 8 $, and $ p(3) = 15 $. For math learners, problem solvers, and professionals tracking emerging digital patterns, uncovering $ p(4) $ reveals not just algebraic skill—but insight into how logic and data converge. This equation, deceptively simple in form, reflects real-world problem modeling across fields like economics, engineering, and design. Its predictive power, hidden in polynomial structure, makes it a puzzle people want to solve for deeper understanding.
Whether stacked inside calculus courses or debated in online forums focused on structured thinking, $ p(x) $ represents a gateway concept: how discrete data points fuel continuous models. Understanding $ p(4) $ isn’t just about plugging into a formula—it’s about recognizing how ooms often balance precision with accessibility.
Understanding the Context
The formula for a quadratic polynomial, $ p(x) = ax^2 + bx + c $, responds naturally to real-world patterns—growth curves, cost functions, scaling dynamics—making this a go-to example in applied learning environments. Its emergence in curiosity-driven searches signals interest not only in results, but in the process: how assumptions shape conclusions, how consistency defines structure, and how small inputs generate meaningful outputs.
Let $ p(x) $ Be a Quadratic Polynomial Such That $ p(1) = 3 $, $ p(2) = 8 $, and $ p(3) = 15 $. Find $ p(4) $.
This quadratic model satisfies three known inputs:
- At $ x = 1 $: $ p(1) = 3 $
- At $ x = 2 $: $ p(2) = 8 $
- At $ x = 3 $: $ p(3) = 15 $
Using these facts, algebra reveals a clear path to $ p(4) $ without guesswork. By substituting values into the general quadratic form and solving the resulting system, we uncover how coefficients determine growth—inside neat equations that hold lasting relevance.

How Let $ p(x) $ Be a Quadratic Polynomial Such That $ p(1) = 3 $, $ p(2) = 8 $, and $ p(3) = 15 $. Find $ p(4) $
This polynomial satisfies the points via substitution into $ p(x) = ax^2 + bx + c $. Setting up equations:
- $ a(1)^2 + b(1) + c = 3 \Rightarrow a + b + c = 3 $
- $ a(2)^2 + b(2) + c = 8 \Rightarrow 4a + 2b + c = 8 $
- $ a(3)^2 + b(3) + c = 15 \Rightarrow 9a + 3b + c = 15 $
Solving this system, subtract equations to eliminate $ c $:
From (2) – (1): $ 3a + b = 5 $
From (3) – (2): $ 5a + b = 7 $
Subtract again: $ (5a + b) - (3a + b) = 7 - 5 $ → $ 2a = 2 $ → $ a = 1 $
Back-substitute: $ 3(1) + b = 5 $ → $ b = 2 $
Then $ a + b + c = 3 $ → $ 1 + 2 + c = 3 $ → $ c = 0 $
Thus, the polynomial simplifies to $ p(x) = x^2 + 2x $.
To find $ p(4) $: $ (4)^2 + 2(4) = 16 + 8 = 24 $.
This elegant result emerges from logical consistency—proof that pattern recognition and algebra work hand-in-hand for forecasting.
Common Questions People Ask About Let $ p(x) $ Be a Quadratic Polynomial Such That $ p(1) = 3 $, $ p(2) = 8 $, and $ p(3) = 15 $. Find $ p(4) $.
Why isn’t $ p(x) $ linear? Because only linear functions maintain a constant first difference. Here, first differences $ 8-3=5 $, $ 15-8=7 $ grow by 2—common in quadratics, where second differences stabilize at $ 2a $. This confirms a curved relationship (nonlinear), validating quadratic assumptions.
Does solving involve complex math? Not at all—safe, straightforward substitution with integer coefficients lowers barriers, making it ideal for mobile learning and discoverable content.
Can this model real-world data? Absolutely: the function mirrors quadratic growth seen in many industries, from revenue projections to physical phenomena—offering practical takeaways beyond theory.
