A. Determine if the ff. relations are functions. Then state the domain and range.
1. { ( 1, -2 ), ( -2, 0 ), ( -1, 2 ), ( 1, 3 ) }
= It is not a function
Domain: { -2 , -1 , 1 , 3 }
Range: { -2 , 0 , 2 , 3 }
2. { ( 1, 1 ), ( 2, 2 ), ( 3, 5 ), ( 4, 10 ), ( 5, 15 ) }
= It is a function
Domain: { 1 , 2 , 3 , 4 , 5 }
Range: { 1 , 2 , 5 , 10 , 15 }
3. { ( 17, ), ( , 17 ), ( 15, ), ( , 15 ) }
= It is a function
Domain: { 15 , 17 }
Range: { 15 , 17 }
4. { ( -3, ), ( -3, ), ( , -5 ), ( 5, ) }
= It is not a function
Domain: { -3 , 5 }
Range: { -5 }
5. { ( , 2 ), ( , 2 ), ( , 2 ), ( , 2 ) }
= It is a function
Domain: { }
Range: { 2 }
B. Evaluate the function.
Let:
6. g ( -1 )
7. g ( -2 )
8. g ( 0 )
9. g ( 5 )
10. g ( - ) remember: ( - = -1 )
