Question

PLEASE HELPP ANYONE
The graph of the function f(x) = −3x^2 − 3x + 6 is shown. Which statements describe the graph? Check all that apply.
A The vertex is the maximum value.
B The axis of symmetry is x = -1/2
C The domain is all real numbers.   
D The range is all real numbers.
E The x-intercepts are at (−2, 0) and (1,0).
F The function is decreasing from (−∞, 6.75).

Answer 1

Answers: 
A, B, C, E.

Everything except D and F.

Answer 2

A The vertex is the maximum value: YES
B The axis of symmetry is x = -1/2: YES
C The domain is all real numbers: YES
D The range is all real numbers.NO. The range is all real number <or= 7
E The x-intercepts are at (−2, 0) and (1,0).YES
F The function is decreasing from (−∞, 6.75): NO. The function is increasing within this interval
