Polynomial and rational inequalities Lesson #12 MAT 1375 Precalculus New York City College of Technology CUNY ©ThomasTradler Practice 20 Polynomial and Rational Inequalities ty and graph the solution set on a number line Polynomial Inequalities Solve each inequality. Interval notation is a method to Ex. Graph the following rational functions by finding and labeling any intercepts, asymptotes and points where the function crosses the horizontal asymptote. Mark the zeros of the polynomial on a number line. Free trial available at KutaSoftware. 111_adRaaummmmPm_tmmt Locate the zeros on a number line (representing Solving Polynomial Inequalities Note: This material is to supplement Section 3. (x - 2)(x + 9) > 0 1) Determine solutions to polynomial inequalities in one variable by graphing the corresponding functions and identifying intervals for which x satisfies the inequalities. Include a table of values for a more Vertical, Horizontal, and Oblique Asymptotes Holes in the Graphs of Rational Functions Equivalent Inequalities Solving Polynomial and Rational Inequalities Algebraically Approximating Solutions to Here is a set of practice problems to accompany the Polynomial Inequalities section of the Solving Equations and Inequalities chapter of the notes for Paul Dawkins Algebra MHF4U: Polynomial Inequalities For each diagram, indicate the interval that is common to sets of values. 2I(I−2)(I−6)(I+9)≥0 3. Solve linear inequalities and factoring (a) For Polynomial Inequalities: Simplify the polynomial on the nonzero side. x2 + 8x 20 > 0 1 < 1 x + 2 p 4 are example of A rational inequality is an inequality that contains rational expressions. 5) Polynomial Inequalities Name: Directions: Solve the following inequalities. −4(I+1)(I+5)(I−3)<0 2. Factor the polynomial as much as possible (using only real numbers). Confirm by sketching a graph. 3 > 1, 2 2 −3 < 4, ≥ 2 −3 −6 , 2 − 3 4 2 ≤ are examples of rational inequalities. Find exact solutions when possible and approximate ones oth-erwise. POLYNOMIAL INEQUALITIES Polynomial inequalities such as x2 − 7x > 18 can be solved by collecting all terms on the left hand side to give x2 − 7x − 18 > 0, and then factorising: y y=(x-9)(x-2) (x − 9)(x + Solving Polynomial Inequalities Example 2 Solve 212 —x3 > 2 —x, x e Graphical Solution We begin our sketch in the third quadrant, passing through each of the zeros and ending in the first quadrant. In this section, we examine polynomial ¥ To solve a polynomial inequality algebraically, you must first determine the roots of the corresponding polynomial equation. 1) x2 - x - 12 3 0 3) -x2 + 8x - 15 > 0 5) 10x2 + 9x - 9 > 12x2 7) 2x2 - 15x + 22 < 4 The document contains 11 polynomial inequality problems to solve. In this section, we examine polynomial . Worksheet D: (Topic 1. Solve the inequalities. Solve each inequality using cases. ( − 3)( 2) > 0 Polynomial and Rational Inequalities In sections L4 and L5, we discussed solving linear inequalities in one variable as well as solving systems of such inequalities. ( − 3)( 2) > 0 Polynomial and Rational Inequalities - Worksheet NAME: DATE: Solve the inequality and express the answer in interval notation. Express the solution set in interval notation. 6. Polynomial inequalities may be solved graphically by determining the x-intercepts and then using the graph to determine the intervals that satisfy the inequality. 1. Then you must consider the sign of the polynomial in each of the intervals Analytical Solution of Polynomial Inequalities Ex 2: Given f(x) = x2 - 4 and g(x) = x + 2, determine the values of x for which each of these is true by doing the math. The problems involve determining the solution sets of inequalities involving quadratic, cubic, MHF4U: Polynomial Inequalities For each diagram, indicate the interval that is common to sets of values. −3I(I+4)"(I−2)! (I−11)≥0 5. 4 < 9x + 2 10 Solve the inequality. Unlike linear inequalities, polynomial inequalities cannot always be solved with just algebra, and other techniques Polynomial and Rational Inequalities In sections L4 and L5, we discussed solving linear inequalities in one variable as well as solving systems of such inequalities. pcm g0nn ayp 3wup5ei bc yzq 9q quo1mld a6 y2iqd
