SSE measures how well the line fits the data.A smaller SSE means the line fits the data points more closely.Here, each squared error shows how far the actual value is from the predicted value, and their sum gives the total error for all points.That’s how you find SSE, step by step, with formulas and calculations! 🚀Roots of a Quadratic EquationMore QuestionsAdd Chart.js in HUGO 📈 Graded AssignmentAssignments$$F(\omega) = \int_{-\infty}^{\infty} f(t) e^{-j\omega t} \, dt$$IIT M FOUNDATION ET1 EXAM QPF1 S2 30 Previous Year QuestionsApr 2023Mathematics for Data Science 1. How many edges are there in a graph with 10 vertices each of degree 6? Solution: In any graph, the sum of degrees of all vertices is twice the number of edges. Sum of degrees = 10 × 6 = 60 So, number of edges = 60 / 2 = 301. 2. What is the minimum number of colours required to colour the given graph? Solution: The answer given is 3. This is a typical graph colouring problem, where the chromatic number is 31.IIT M FOUNDATION ET1 EXAM QPF2 S2 30 Previous Year QuestionsApr 2023Mathematics for Data Science 1. How many edges are there in a graph with 10 vertices each of degree 6? Solution: Sum of degrees = 10 × 6 = 60. Each edge is counted twice, so number of edges = 60 ÷ 2 = 30[^1]. 2. What is the minimum number of colours required to colour the graph given below? Solution: The answer is 3. This is the chromatic number, meaning three colours are needed so that no two adjacent vertices share the same colour[^1].IIT M QUALIFIER AN EXAM QDQ1 27 Oct 27 Oct 2024PYQMathematics for Data Science 1️⃣ Polynomial Limits Question Question: Consider the polynomials $ p(x) = x^3 - 3x^2 + 100x - 1 $ and $ q(x) = x^3 + x + 5 $. Which of the following statements are correct? Correct Statement: $ p(x) - q(x) \to -\infty $ as $ x \to \infty $ ✅ Solution with Steps: Find the leading terms: Both $ p(x) $ and $ q(x) $ have $ x^3 $ as the highest degree term. Subtract the polynomials: $ p(x) - q(x) = (x^3 - x^3) + (-3x^2 - 0) + (100x - x) + (-1 - 5) = -3x^2 + 99x - 6 $ Analyze as $ x \to \infty $: The highest degree term is $ -3x^2 $. As $ x \to \infty $, $ -3x^2 \to -\infty $. Conclusion: So, $ p(x) - q(x) \to -\infty $ as $ x \to \infty $. 🎯 Final Answer: Option 2 is correct![^1] 2️⃣ Polynomial Graph Matching Question: Given $ p(x) = 0.3x^3(x^2 - 1)(x - 2)^2(x - 3) $, which figure represents the polynomial $ p(x) $?IIT M QUALIFIER AN EXAM QDQ2 27 Oct 27 Oct 2024PYQMathematics for Data Science Question 1 Question: Consider the polynomials $ p(x) = x^5 - 3x^4 + 100x - 1 $ and $ q(x) = x^5 + x + 5 $.
