12. The quadratic equation y = 3(x + 4)' - 5 is written in 17. Solve the quadratic equation 2x - 6x = 5 correct to two decimal places. standard form. A) 3.68 B) 5.5 C) 3.68 & -0.68 D) No Solutions vertex form. factored form. slope y-intercept form 18. Put the equation y = 2x*- 12x + 7 into vertex form. Aj y = 2(x -3)2 +7 B) y = 2(x - 6)? - 11 C y = 2(x - 3)? - 11 D) Can't 13. Which of the following equations defines the following quadratic function ? A) y = -2(x - 1) + 3 Part B: True/False (10 marks) Answer the following on the Google Form. Each answer is worth 1 mark. B) y = -2(x + 1) + 3 1. The vertex of y = -2(x+ 3)* -5 is (3, -5) T/F q y= -(x - 1) - 3 2. The function y = x has been translated 6 units to the right and 2 units down. The new equation is y = (x - 6) - 2 T/F D) y = - H(x + 1) - 3 3. When you evaluate 32' you get and answer of 2. T/F 14. Which one of the following functions has a maximum value ? 4. f(x) = -4x + 5x - 16 can't be factored. T/F f (x) = 2x - 3 When you factor you get_ B ) g(x) = x - 9x + 18 5. x +8x+7 , (x+8)(x+1) T/F C) h(x) = -2(x + 3) - 4 6. 6x' -18x , 6x(x - 3) T/F DJ y = 10' 7. Given the function y = 4x , the transformation is a vertical compression. T/F 15. A quadratic function has no real roots when : the value of the discriminant is negative 8. The y-intercept for y = 2" is (0,1). T/F the value of the discriminant is positive the vertex is below the x-axis and the parabolas opens up 9. The following relation is a function? the vertex is above the x-axis and the parabola opens down y= -(x-1)' T/F 16. The equation for the axis of symmetry for the function defined by y = 3(x + 6) - 2 is : X =6 X=-6 y = 6 D) y = -6 Page 3 of 9 Page 4 of 9
