Question

Suppose that the relation G is defined as follows.

G = {( 5 ,0 ), (7,-7 ), (-8,-7 ) }

Give the domain and range of .
Write your answers using set notation

Answer 1

DOMAIN { 5,7,-8}
RANGE {0,-7,-7 }
right ?

Answer 2

You got it :)

Answer 3

r (x ) = x+3 ; s(X) = 4x^2
(r * s) (x)= 4x^3 +12x^2

Answer 4

I hope is right...

Answer 5

(r-s) = -4x^2 +x+3
(r+s)(-1) = 4(-1)^ + -1 +3

Answer 6

(r+s)(-1) = 6
