TSIA2: Algebraic Reasoning Exam Questions and Answers | Latest Version 2026 | Graded A+ What is the difference between a function and a relation? - answer-A function is a specific form of relation where every value of has only one value of that makes the relation true. Explanation: y=2x is a function because for each value of x, there is only one value that equals 2x. y2x is a relation because for each, many values are less than 2x. In a linear equation of the form y=mx+b, what does m represent? - answer-m represents the slope of the line. What is meant by the "degree of a polynomial"? - answer-The degree of a polynomial is the highest. Explanation: The degree of the polynomial 4x^2+2x^3 is 3. If a polynomial is in the form x^2+2xy+y^2 , what is its factored form? - answer-(x+y)(x+y)=(x+y)^2 True or false? In an inequality, multiplying or dividing by a negative number reverses the inequality sign. - answer-true What are the three different solution sets of a system of linear equations? - answer-no solution, a unique (one) solution, and infinite solutions To evaluate the function f(x)=3x-2(x-1) at x=2, we will ______. - answer-Substitute 2 into all the x values of the function and solve by using the order of operations. The exponential model P = 100 (1.3)^5 represents the city's population after a certain number of years. What does 1.3 represent? - answer-It represents the growth factor of the population with a 30% growth rate per year.Quadratic Equation - answer-An equation that can be expressed in the standard form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0. Standard Form - answer-The format of a quadratic equation written as ax² + bx + c = 0, highlighting the coefficients of the terms. Coefficient - answer-A numerical or constant quantity placed before and multiplying the variable in a term of an equation. Roots - answer-The values of the variable that satisfy the quadratic equation, also known as solutions or zeros of the equation. Discriminant - answer-The part of the quadratic formula under the square root sign, calculated as b² - 4ac, which determines the nature of the roots. Vertex - answer-The highest or lowest point of the parabola represented by a quadratic equation, found at the coordinates (-b/2a, f(-b/2a)). Parabola - answer-The U-shaped graph that represents a quadratic function, which can open upwards or downwards depending on the sign of a. Factoring - answer-A method of solving quadratic equations by expressing the equation as a product of its linear factors. Quadratic Formula
