do all 5of them thank you!

4. Determine whether each function is even, odd or neither. a. f (x) = 6x5 - 2x b. f (x) = x2 + 3cosx. c. h(x) = x3V1+ x2 5. If f ( x) = it find fl (x). Show that f(f* (x)) = x 6. Given f(x) = x2 - 1 and g(x) = x2 + 1, find (fog)(x) 7. Sketch the function f (x) = x2 and use your study of transformations to graph g(x) = (x - 1) + 2 on the same graph. 8. If f(x) = x2 -4 and g(x) = x2 + 3x -4, find: a. (f+g)(x) b. (f - g)(x) c. (fg) (x)
