Ex: Give the Domain and Range Given the Points in a Table


– THE FUNCTION
F OF X IS DEFINED IN THE TABLE BELOW. USING THE TABLE
IDENTIFY THE DOMAIN AND THE RANGE OF THE FUNCTION. WE’RE ASKED TO WRITE THE ANSWERS
AS A ORDERED LIST ENCLOSED IN CURLY BRACKETS. FOR REVIEW, THE DOMAIN IS A SET
OF ALL POSSIBLE INPUTS, OR IN THIS CASE, THE X VALUES. AND THE RANGE IS A SET OF ALL
POSSIBLE OUTPUTS OR Y VALUES, WHICH WOULD BE
THE FUNCTION VALUES. AND THEREFORE, THIS COLUMN
REPRESENTS THE POSSIBLE INPUTS OR THE DOMAIN, AND THIS COLUMN
REPRESENTS THE POSSIBLE OUTPUTS OR FUNCTION VALUES,
WHICH WOULD BE THE RANGE. SO WE’RE ASKED TO INCLUDE
THE DOMAIN AND RANGE IN A SET OF CURLY BRACKETS,
WHICH LOOK LIKE THIS. WE DO WANT TO LIST THE DOMAIN
OR THE X VALUES IN ORDER FROM LEAST TO GREATEST. NOTICE HOW THEY ALREADY ARE
IN ORDER FROM LEAST TO GREATEST, BUT IF THEY WEREN’T
WE WOULD WANT TO ORDER THEM FROM LEAST TO GREATEST. SO WE HAVE
{-3, -2, -1, 0, 1, 2, 3.}. THIS WOULD BE THE DOMAIN
OF F OF X. AND THE RANGE IS A SET
OF ALL POSSIBLE OUTPUTS, WHICH ARE GIVEN HERE. NOTICE HOW WE DO WANT
TO LIST 2 FIRST ‘CAUSE IT’S THE SMALLEST VALUE. THEN NOTICE HOW 3
WOULD BE THE NEXT VALUE. IT DOES OCCUR TWICE,
BUT WE DO NOT LIST THE REPETITION,
WE ONLY LIST IT ONCE. FROM THERE, WE WOULD HAVE 6
AND THEN 11. THIS IS THE DOMAIN
AND THIS IS THE RANGE OF THE GIVEN FUNCTION F OF X. I HOPE YOU FOUND THIS HELPFUL.
