1. The following equations are in STANDARD FORM. Identify the values of a, b and c for each. a y = 2x2 +4x +8 a= b= C= by = x2 +9x -6 a= b= c) y=-x2 - 2x a= b= d) y=_x2 -16 a= b= 2. The following are the same equations from question #1. Circle the appropriate response or fill in the blank. a y = 2x2 +4x+8 Opens : U or D Max or Min y-int : by = x2 + 9x- 6 Opens : U or D Max or Min y-int : c) y=-x2 - 2x Opens : U or D Max or Min y-int : d) y=_x2 -16 Opens : U or D Max or Min y-int : 3. The following quadratic equations are in FACTORED FORM. Fill in the following chart. You will need to do some work on a scrap piece of paper... Direction of Coordinates x-intercepts Max/Min value y-intercept of the vertex Opening a) y = (x- 3)(x- 1) Max Min b) y = - (x+1)(x+9) Max Min C y=-2(x-4)(x+2) ( , Max Min dj y = ~ x(x+6) ( , Max Min 4. Use your information from #3 to graph the ABOVE equations on the grids below. WW
