Given the functions below, find (g-f)(x) and give its domain. f(x) = x + 2x -7x-1; g(x) = x-x + 4x A. It is odd and symmetric to the origin. B. Odd and symmetric to the y-axis. C. Even and symmetric to the origin. D. Even and symmetric to the y-axis. 23. Given the functions below, find (f + g)(x) and give its domain. 2 f(x) = x 5; 8(x) = -- x+5' x (g- f)(x) = Domain: (f +g)(x) = Domain: 24.
