1. Which equation is y = (x + 3) + (x + 4) rewritten in vertex form? y = 2 y = 2(x + 7) 73 y = (x + 7) 24 2. Which equation has a graph that is a parabola with a vertex at (5, 3)? y = (x 5) + 3 y = (x + 5) + 3 y = (x 3) + 5 y = (x + 3) + 5 3. Which equation has a graph that is a parabola with a vertex at (1, 1)? y = (x 1) + 1 y = (x 1) 1 y = (x + 1) + 1 y = (x + 1) 1 4. Which equation is y = 3x 12x 2 rewritten in vertex form? y = 3(x + 2) + 10 y = 3(x 2) + 10 y = 3(x + 2) 14 5. Which phrase best describes the translation from the graph y = (x + 2) to the graph of y = x + 3? 2 units left and 3 units up 2 units left and 3 units down 2 units right and 3 units up 2 units right and 3 units down 6. What is the first step when rewriting y = 3x + 9x 18 in the form y = a(x h) + k? 3 must be factored from 3x + 9x x must be factored from 3x + 9x 9 must be factored from 9x 18 3 must be factored from 3x 18 7. Which equation is y = 2x 8x + 9 rewritten in vertex form? y = 2(x 2) + 9 y = 2(x 2) + 5 y = 2(x 2) + 1 y = 2(x 2) + 17 8. What is the first step when rewriting y = 6x + 18x + 14 in the form y = a(x h) + k? 16 must be factored from 18x + 14 x must be factored from 6x + 18x 6 must be factored from 6x + 14 6 must be factored from 6x + 18x 9. Which phrase best describes the translation from the graph y = 6x to the graph of y = 6(x + 1)? 6 units left 6 units right 1 unit left 1 unit right 10. What is the first step when rewrit
