D Question 9 Two functions are given below. f (x) = -2x2 + 4x +1 9 (x) = 5x - 3 What is the value of -4f (x) - g (x)? O 8r2 - 9x + 1 O 8x2 - 13x + 2 O 8x2 + 11x -7 O 8x2 - 21x - 1 D Question 11 5 pts Given the function f(x) = x3 + 3 and g(x) = 2x3 - 1, which describes the transformations applied to the function f(x) so it falls onto g(x)? The graph of g(x) has a vertical stretch by a factor of 2 and a vertical shift down 1 from the function of f(x). O The graph of g(x) has a vertical stretch by a factor of 2 and a vertical shift down 4 from the function of f(x). The graph of g(x) has a vertical shrink by a factor of 2 and a vertical shift down 1 from the function of f(x). The graph of g(x) has a vertical shrink by a factor of 2 and a vertical shift down 4 from the function of f(x).
