how do I combine this function?
if f(x)=x^2+5x6 and g(x)=x1, find (f.g)(x) and (f/g)(x)

Best ResponseYou've already chosen the best response.0For the second part, (f/g)(x), just use long or synthetic division. It is saying to divide f(x) by g(x). You should get (x + 6) as you answer. The first part of the problem is unclear. Is it saying f(g(x)),which means f of g of x, or is it saying f(x) times g(x)?

Best ResponseYou've already chosen the best response.0Well if it was (fog) which means the same thing as f(g(x)), Then just sub the function g(x) wherever you see an 'x' in the f(x) function. You should get: x^2 +3x 10 Or in factored form... (x+5)(x2) 2. If it was (f*g)(x), meaning f times g, Then multiply the two functions and obtain a polynomial to the 3rd degree: (x^2 +5x  6)(x1) = x^3 + 6x^2  11x +6 Or in factored form... (x1)(x1)(x+6)
