Circle the correct answer. (5 marks) 1. Which graph represents a quadratic relation? 2 of 6 3. The relation y = -2(x + 4)" - 3 has A a maximum at (4, -3) B a minimum at (4, -3] a maximum at (-4, -3] a minimum at (-4, -3) 4. The graph shows the path of a soccer ball after it was kicked. The x-values represent the horizontal distance travelled and the y-values represent the height of the ball, bath in metres. How far does the ball travel before it hits the ground? A 10 m B 20 m C 40 m Dum 2. Which of these quadratic relations opens upward? A y=-3[x+ 4) B y = 0.25x - 1 5. Which set of transformations to the graph of y = >' would give the C y = 3[x+ 2) + 5 D Both B and C parabola y= -3(x -21 + 57 A A reflection in the x-axis, a vertical stretch by a factor of 3, translation of 2 units right and 5 units up. 3 A reflection in the x-axis, a vertical stretch by a factor of 3, a translation of 2 units left and 5 units down. C A reflection in the y-axis, a vertical compression by a factor of 3, a translation of 2 units right and 5 units up. D A reflection in the y-axis, a vertical compression by a factor of 3, 3. The relation y = -2(x + 4) - 3 has a translation of 2 units left and 5 units up. A a maximum at [4, -3] B a minimum at (4, -3) C a maximum at [ 4, -3) D a minimum at (-4, -3] 4. The graph shows the path of a soccer ball after it was kicked, The x-values represent the horizontal distance travelled and the p-values represent the height of the ball, both in metres. Provide complete solutions to achieve full marks. 6. For the given parabola determine the coordinates of the vertex. Then write an equation for the relation in the form =a(x -5)" + &. (5 marks) How far does the ball travel before it hits the ground? A 10 m B 20 m C 40 m S. Which set of transformations to the graph of y = x would give the parabola y =-3(x - 21 + 5? A A reflection in the x-axis, a vertical stretch by a factor of 3, translation of 2 units right and 5 units up. (C) B A reflection in the 2-axis itical stretch by a factor of 3, a 7. Determine which relation is linear, quadratic of neither. Justify your translation of 2 units left and answers. (9 marks) y=x*+4 hi
