You have several options: Use the Word tools; Draw the graph by hand, then photograph or scan your graph; or Use the GeoGebra linked on the Task page of the lesson to create the graph; then, insert a screenshot of the graph into this task. 1. Find the axis of symmetry for y = 4x 2 + 16x - 2. x = -2 a. x = 2 b. x = -2 c. x = 8 d. x = -8 2. Find the axis of symmetry for y = -x 2 - 9x + 4. x = 9 2 2 a. - 9 b. -18 9 c. 2 9 d. - 2 x x x x 3. Find the vertex of y = 3x 2 + 12x + 2. (-2, -10) a. (2,38) b. (-2,-10) c. (-2, -34) d. (2, 36) 4. Find the vertex of y = -2x 2 - 3x - 1. ( 3 4 , 1 ¿ a. ( 3 4 , 1 8 ) b . ( 3 4 , 1 )
c. ( 3, 10 ) d. ( 3, 28 ) 5. Find the x-intercept(s) of y = x 2 - 5x - 14. (7, 0) and (-2, 0)
6. Find the x-intercept(s) of y = 3x 2 + 10x - 8. ( 2 3 , 0 ¿ ∧(− 4,0 ) ) ) ) )
