for the given functions f and g, find the composite fundtions f0g and g0f and state their domains: f(x)=2x+1 g(x)=x(squared)-3 Answer The composite fog(x) is
f(g(x)), which means take g and put it in for x in f. The composite g0f(x) is g(f(x)), which means take f and put it in for x in g. Here, f(x) = 2x+1 and g(x) = x²-3. f(g(x)) = 2g(x) + 1 = 2x² - 6 + 1 = 2x² - 5. g(f(x)) = f...
