RELATIONS OR FUNCTIONS
Answer:
What do we mean by relations? it is a set of mapping of domain and range, sets of values.
How about functions? a relationship between one variable- dependent and independent variable.
Step-by-step explanation:
Determine which of the following relations, is a function.
- S = { (3,2), (2,2), (1,2) }
Domain : { 3, 2, 1 }
Range : { 2, 2, 2 }
- This relations is not a function.
====================================
- M = { (-1, 0), (-2, 1), (-3, 2), (-2, 3) }
Domain : { -1, -2, -3, -2 }
Range : { 0, 1, 2, 3 }
- This relations is a function.
====================================
- A = { (4,2), (8,4), (16,8) }
Domain : { 4, 8, 16 }
Range : { 2, 4, 8 }
- This relations is a function.
====================================
- R = { (-5,-6), (-5,-12), (-5,-15) }
Domain : { -5, -5, -5 }
Range : { -6, -12, -15 }
- This relations is not a function.
====================================
- T = { (10,-5), (15,0), (20,5)
Domain : { 10, 15, 20 }
Range : { -5, 0, 5 }
- This relations is a function.
