Find the range of the function for the given domain. F(x) = 2x - 7; {-2,-1, 0, 1, 2}

OpenStudy (kendricklamar2014):

@StudyGurl14 @chosenmatt @HelpBlahBlahBlah

OpenStudy (anonymous):

plug in x values from -2,-1,0,1,2 in F(x) and see the values @KendrickLamar2014

OpenStudy (kendricklamar2014):

How do u do that @Princer_Jones

OpenStudy (anonymous):

for x=-2, F(x)=2(-2)-7=-11 similarly put the values @KendrickLamar2014

OpenStudy (studygurl14):

Looks like @Princer_Jones has this handled... :)

OpenStudy (kendricklamar2014):

So what's the next step??

OpenStudy (anonymous):

next put -1,0,1,2 and see the respective values.. The set of all those values form the range. @KendrickLamar2014

OpenStudy (kendricklamar2014):

ohh, give me a sec

OpenStudy (kendricklamar2014):

So 2 - -1 = the range??

OpenStudy (anonymous):

{-11,-9,-7,-5,-3} is the range

OpenStudy (anonymous):

the set of all F(x) values forms the range

OpenStudy (kendricklamar2014):

So {-11,-9,-7,-5,-3} is the answer??

OpenStudy (anonymous):

yeah

OpenStudy (kendricklamar2014):

thanks
