if you need just tell me and i will come to the rescue.

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
