9:05 .1 5G8 1 of 2 QUADRATIC EQUATIONS STANDARD FORM NAME Rewrite each quadratic equation in standard y = a(h- h) + k form. Graph each equation. Identify the vertex, y-intercept and algebraically determine the x-intercepts. Check using your graphing calculator. 1. y = 2x2 +12x+10 2. y = 3x -12x+9 . y = 2 ( x 4 3 ) - 8 y = 3 ( x-2 ) - 3 x-int: - and - 5 x-int : 3 and / 3. y=-x2 - 6x-8 4. y = 3x2 -6x-7 . = - 1 (x+2) +1 y = 3 ( x-1 ) - 10 x-int: -2 and - 4 x-int: 1 1 30 31 1 30 3 3 5. y=-4x2 +8x+5 6. y= 2x3 +12x+9 y = - 4 ( x - 1 ) + 9 y = 2 ( x + 3 ) - 9 x-int: a and - 2 xint : - 31 3 52 - 6+ 3 12 Z or 2 7. y=-x' -4x+3 8. y =-x +5x+6 y = - 1 ( * +2 ) +7 y = 2 ( x+s ) - 12 0 04-7g-docs.googleusercontent.com C
