2 1 Relationsfunctions Ppt Describe a method of visual inspection for determining if a given relation is an onto function, a one to one function or neither. match each domain element to the correct range element by drawing a line between the two. use the function f(x) = 3x2 x 5. look up the words dependent and independent in a dictionary. Graph each relation or equation and determine the domain and range. determine whether the relation is a function, is one to one, onto, both, or neither. then state whether it is discrete or continuous. d = {2}, r = {–3, –1, 4}; no; discrete . 12. f(–2) – 5 13. g(–1) 1 . d = {2, 6}, r = {2, 6}; yes, both; discrete. Graph each relation or equation and determine the domain and range. determine whether the eqation is a function, is one to one, onto, both, or neither. then state whether it is discrete or continuous. 5. {(2, 3), (2, 4), (2, 1)} 6. {(2, 6), (6, 2)} 7. {( 3, 4), ( 2, 4), ( 1, 1), (3, 1)} 8. x= 2 find each value if f(x) =2x 1 and g(x) =2 x2. 9. Relations and functions a relation can be represented as a set of ordered pairs or as an equation; the relation is then the set of all ordered pairs (x, y) that make the equation true. a function is a relation in which each element of the domain is paired with exactly one element of the range. element of the range.

Example 2.7 : let a = {1, 2, 3, 4, 5, 6}. define a relation r from a to a by r = {( x, y) : y = x 1} and write down the domain, range and codomain of r. solution : r = {(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)} domain of a = {1, 2, 3, 4, 5} range of r = {2, 3, 4, 5, 6} and codomain of r = {1, 2, 3, 4, 5, 6} check your progress 2.1 1. Goals: #1 i can determine whether a relation is a function. #2 i can state the domain and range of a relation. #3 i can determine whether a function is linear and evaluate functions for given. Students will practice classifying relations (functions vs relations) from graphs, equations and ordered pairs. also, students will identify the domain and range of a given relation function. example questions. 1. plan objectives 1 to graph relations 2 to identify functions examples 1 graphing a relation 2 finding domain and range 3 making a mapping diagram 4 identifying functions 5 using the vertical line test 6 real world connection math background a relation between two sets of numbers can be represented by a set of ordered pairs. the first.
