Answer:
(-2,2)
Step-by-step explanation:
Let's find the answer.
Because a tangent line for a parabola function is equal to 0 only at its vertex then:


so then:
when


For x=-2 f(x) is:



In conclusion, the vertex of the given parabola is (-2,2), so the answer is C. Although in your answer is reported as (-2.2) but I think was a typing mistake.
It should be B. 15.
I think ..
Substituting y=x-6 into the equation,
3x + 2(x-6) = 3x + 2x - 12 = 5x - 12
5x - 12 = 8
5x = 20
x = 4
