OpenStudy (helpsos):
Substitute for f and g so you should have (fg)(x) = (4x + 7) (2x * 2)
OpenStudy (helpsos):
do you know how to multiply these two equations?
OpenStudy (helpsos):
Also, is g(x) equal to 2x*2?? Because that can be simplified to 4x
OpenStudy (marcelie):
no.
OpenStudy (marcelie):
so then the g(x) goes inside the 4(...)^2 +7
