ANSWER THE FOLLOWING:

III. Determine whether or not each equation defines y as a function of x. If it is a function, find its domain and range. 14. x+y=9 16. x2 + y = 16 18. 2x = yz 15. x + y = 8 17. x2 + y? = 9 19. y = Vx +2 IV. Find the domain and range of each relation. 3 7x 20. f(x) = 4x2 + 3x -1 22. g(x)= 24. h(x)= x + 4 x2 - 25 21. g(x) = 2 5x 21 x2 - 16 23. h(x) = x2 - 9 25. f(x) = (x + 8)(x - 4)
