Answer:
The correct answer is C.
Step-by-step explanation:
To find the line of symmetry, we use the equation:
-b/2a
In this equation, a is the coefficient of x^2 and b is the coefficient of the x term.
-b/2a
-6/2(-2)
-6/-4
1.5
Now we know that 1.5 is the line of symmetry, which gives us C as the only possible answer.
