np

OpenStudy (anonymous):

do you know what to do if its inverse of f(x)

OpenStudy (anonymous):

umm maybe can u post question

OpenStudy (amistre64):

f(x)={(3,5),(2,4),(1,7)} ; there is no spot to modify "x" in this; so its pretty much considered a constant

OpenStudy (anonymous):

f(x)={(3,5),(2,4),(1,7)} f^-1(x)={(5,3),(4,2),(7,1)}

OpenStudy (anonymous):

x and y values switch

OpenStudy (amistre64):

the only way this makes sense is of you define what it means to begin with :)
