Let f (x) = –5x + 3 and g(x) = 6x – 2. Find f • g and its domain...

OpenStudy (anonymous):

f(g(x)) does that help

OpenStudy (anonymous):

f • g means replace every variable in F(x) with G(x)

OpenStudy (anonymous):

so -5(6x-2)+3

OpenStudy (anonymous):

-30x+10 +3 -30x+13

OpenStudy (anonymous):

the domain is all x values. so think of it this way, what x values can you put into that function to get a real number?
