Use the given functions f and g to find f + g, f-g, fg, and fg. State the domain of each. (Enter your answer for the domain in interval notation.) f(x) = 3x + 6, g(x) = x + 2. Find the domain of each problem. f+ g = Domain= f-g= Domain= (f)(g)= Domain= f/g-Domain= 2.) Find (g = f(x) and (fog)(x) for the given functions fand g. f(x) = 3/(x+5), g(x) = 3x - 6 (gof)(x) = (fog)(x) = 3.) Use the method of completing the square to find the standard form of the quadratic function. f(x)=x²-8x+2 y= 4.) Use the vertex formula to determine the vertex of the graph of the function. f(x)=x²-14x Write the function in standard form. f(x) = 5.) Use the vertex formula to determine the vertex of the graph of the function. f(x) = 3x² - 10x + 1 Write the function in standard form. f(x) = Use the given functions f and g to find f + g, f-g, fg, and fg.
