The vertical Line test. If slope is 2, slope of perpendicular line = – 1 / 2. iii. Passing the vertical line test means it only has one y value per x value and is a function. To perform a vertical line test, draw vertical lines that pass through the curve. For the curve to pass the test, each vertical line should only intersect the curve once. Perpendicular lines: The slopes of perpendicular lines are negative reciprocals. ... A Vertical Line Test is used to determine if a relation is a function. graphs i and ii. the official math cheat sheet for the final stephanie sorosiak functions function: rule that assigns to ie. C. A . all terms by common denominator. graph iii. Solving Rational Equations: Get rid of the denominators by mult. is a way to determine if a relation is a function. ☐ Can’t perform test (test stopped or not requested for suspect’s safety); Note only the clues observed. Identify Functions and the Vertical Line Test Read from Vertical Line Test Worksheet, source:ck12.org. A set of ordered pairs in which each x element has only one y element f (x) = 3x + 4 f (3) = 3•3 + 4 = 13 Systems: y – 2x = 1 y + 2x = 9 Linear: substitute; add to eliminate one variable or graph. Step 3 : In the above graph, the vertical line intersects the graph in at most one point, then the given graph represents a function. Functions Cheat Sheet Name _____ Exponents are shorthand for repeated multiplication of the same thing by itself. Name Definition Formulas Simple y = x2 –x-6 y = 2x – 2 Linear Quadratic: substitute or graph Identifying Functions using the Vertical Line Test If a graph represents a function, that graph will only intersect with a vertical line one time. The vertical line test is a test to see if graph is linear. Be familiar with the Binomial Theorem, which states that (a+b)n= n 0 an+ n 1 an 1b+ n 2 an 2b2+ + n n 1 abn 1+ n n bn: Total Clues: ☐ (Decision Point: 2; Max: 4) Walk and Turn Instructions Stage: ☐ Place your left foot on a line, (real or imaginary) and put your right heel against the … Distance formula: point vertical line test: unique for each like this Horizontal line: y = h [h is any constant value] Vertical line: x = v [v is any constant value] Point-slope formula: (y – y 1) = m(x – x 1) Parallel lines: Parallel lines have the same slope. Which graph from question 2 is linear? graph i. (Vertical line test) 2.2.1 Polynomials Make sure you at least know what a polynomial is. graphs ii and iii. 2. Place on number line, and test sections. i. ii. If you think about it, the vertical line test is simply a restatement of the definition of a function. We have to check whether the vertical line drawn on the graph intersects the graph in at most one point. D . A relation is a function if there are no vertical lines that intersect the graph at more than one point. Function Notation can be written as: f(x) = 3x+2 this translates to: “f of x” equals 3x+2” g(x) = 3x-1 this translates to: “g of x equals 3x – 1” Evaluating Functions The horizontal line test is the vertical line test but with horizontal lines instead.

Problem 2 : Use the vertical line test to determine whether the following graph represents a function. Function: Passes the vertical line test.
