9.1. For the sets A = {a,b, c} and B= {r, s,t,w}, let R = {(a, s), (a, t) , (b,t)} be a relation from A to B. Determine dom (R) and range (R).

4. Use first or second differences to determine the type of relation between x and y. 5 -1 2. 1 4. a) linear b) neither linear nor quadratic c) quadratic d) unable to determine 5. The graph of the quadratic relation y = x - 3x – 4 is shown below. For what value or values of x is y = 0? 5. a) x= -1 only b) x= -1 and x = -4 c) x = -4 only d) x= -1 and x = 4 6. The graph of y = x* is translated 3 units to the right. The equation for this new graph is 6. a) y=x² +3 b) y= 3x? c) y =x³ -3 d) y = (x-3)? 7. Decide which direction the graph of y = -x -6 opens, its vertex point, and what its translation from y =x is. 7. a) opens down, vertex at (0, -6), shifted b) opens down, vertex at (-6, 0 ), shifted down 6 units up 6 units c) opens up, vertex at (0, -6), shifted up 6 d) opens up, vertex at (-6,0), shifted units down 6 units 8. Which of the following equations represents an exponential relation? (Ready for Gr.11!? O) 8. a) y=x? b) y=x c) y= 6" d) y =x³ + 2x2 – 5x +1
