Best ResponseYou've already chosen the best response.1f(x)=15x+1 g(x)=15x^220x5 f(3) = 15(3) + 1 = 45 + 1 = 46 (g o f)(3) = g(f(3)) = g(46) g(46) = 15(46)^2  20(46)  5 = 31740  920  5 = 32665

Best ResponseYou've already chosen the best response.1The general formula is: (f o g)(x) = f(g(x)) But in this case we have: (g o f)(x), so we write: (g o f)(x) = g(f(x)), then solve.
