What is the domain of the relation shown below ( 4-,-2)

The domain of a relation is the set of input values, the relation can take

The domain of the relation is {0,1,4}

The ordered pair of the relation is given as:

( 4,2),(1,1),(0,0),(1,-1),(4,-2)

Rewrite as:

(x,y) = ( 4,2),(1,1),(0,0),(1,-1),(4,-2)

Remove the y values

x, = { 4,1,0,1,4}

Remove repetitions

x, = {0,1,4}

Hence, the domain of the relation is {0,1,4}

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
