How many batches of brownies can you make with 2 cups of sugar?

Depends how big the batches are, is this a multi choice or one that you write?

Step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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)
