A. left 2 units
the vertex form of a parabola is 
y = a(x-h)^2 + k
(h,k) is the point of the vertex
since h is -2 in (x+2)^2
the function is shifted 2 units left

Answer:
The answer to your question is No
Step-by-step explanation:
Data
function f(x) = 2x³ + x² - 10x - 12
To know if a number is a root of a function, evaluate the function on that number, if the result is zero, then that number is a root.
Substitution           
                f(-2) = 2(-2)³ + (-2)² - 10(-2) - 12
Simplification           
                f(-2) = 2(-8) + 4 + 20 - 12
                f(-2) = -16 + 4 + 20 - 12
                f(-2) = -28 + 24
                f(-2) = -4
-2 is not a root that the function.

<u>Statement                                                        Reason                               </u>
∠5 and ∠7 are vertical angles                        Vertical angles theorem
m∠5 = m∠7                                                      Definition of vertical angles
m∠5 = -2(3x - 4), m∠7 = 3(x - 3) - 1                  Given
-2(3x - 4) = 3(x - 3) - 1                                       Substitution property of equality
-6x + 8 = 3x - 9 - 1                                            Distributive property
3x + 6x = 8 + 10                                               Addition property
