Rang : {2, 4,6,8}
Ans C
what is the range of the relation below?
((1,2)(3,4)(5,6)(7,8))
a)all real numbers
b) all even numbers
c)(2,4,6,8)
d)(1,3,5,7)
I am confused because I thought the range was the highest - the lowest number.
so if it was the highest 8-1, the lowest, the answer would be 7.
if you do each set separately each answer is 1
either way I would say a) they are all real numbers.
Is this correct? If not could you lead me in the correct direction of what to do. Thanks

The range by definition is a set that contains all the y values .
ok, so the first number is the x value and the second is the y value?
Thank you for explaining that.
