Question 1a: Write the following quadratic function in the following forms: y=2x2 - 9x - 5

(a)Standard Form:
 y=2x2 - 9x - 5

(b) Vertex Form
 y=2(x - 9/4)2 - 121/8

(c) Zero Form:
 
 y=2(x -5)(x + ½)

Question 2a: Write the following quadratic function in the following forms: y=-3(x+3)(x-2)

(a)Standard Form:
  y = -3x2 -3x + 18

(b) Vertex Form
 y = -3(x+½)2 +18.75

(c) Zero Form:
 y = -3(x+3)(x-2)

Question 1b: Write the following quadratic function in the following forms: y=-0.6x2 -1.2x +4

(a)Standard Form:
 y=-0.6x2 -1.2x +4

(b) Vertex Form
 y = -0.6(x + 1)2 + 4.6

(c) Zero Form:
 
  y = -0.6(x + 3.7689)(x - 1.7689)

Question 2b: Write the following quadratic function in the following forms: y=-12(x+6)2 +12

(a)Standard Form:
 y = -12x2 -144x - 420

(b) Vertex Form
 y = -12(x+6)2 +12

(c) Zero Form:
 
  y = -12(x+5)(x+7)
