The google activity may be edited if needed (add/delete questions, change answer type, etc.) For example, the ordered pair \((4, 3)\) represents the position \(4\) units to the left of the origin, and \(3\) units above in the second quadrant. Therefore, \(x = |y| + 1\) does not define a function. so will it will not be a function because -4 will have to pair up with -3. The Vertical Line Test: Given the graph of a relation, if a vertical line can be drawn that crosses the graph in more than one place, then the relation is not a function. TPT empowers educators to teach at their best. 15If any vertical line intersects the graph more than once, then the graph does not represent a function. 4.2 Relations and Functions A function is a relation in . /SM 0.02 Functions and relations answer key - Section 5.2 Defining Relations and Functions.
