Answer to Question #56448 in Algebra for Box Cars

Question

5: Which of the following represents this function written in standard form. There can be multiple right answers. Check all that apply.
Y= 2(x+1)(x-6)

Y=2x^2 - 10x - 12

Y= 2x^2 - 10x +6

Y= 2x^2 -5x -12

Y=2x^2 -14x +12
---------------------------------------...
6: Which of the following represents this function written in intercept form? There can be multiple right answers. Check all that apply.
Y = - x^2 – x + 6

y = -(x – 2)(x + 3)

y = -(x + 2)(x – 6)

y = -(x + 2)(x + 6)

y = (-x + 3)(x – 4)

7: What are the coordinates of the vertex of the function below? Write the answer in the form (x,y)
y + 9 = -6(x - 2)^2
