A company that produces strawberry, grape, and raspberry jam tracked the costs to make each type of jam each year. The cost to make a container of each type of jam increased, including supply costs. The costs, in dollars, to make a container of the strawberry jam and the grape jam are represented by the functions shown, where x represents the number of years since the company opened. Strawberry Jam: $$s(x)=3.10+0.05x$$ Grape Jam: $$g\left(x\right)=0.01\left(x-1\right)^2+2.95$$ The graph of the exponential function r(x) shown on the coordinate grid represents the cost, in dollars, to make a container of the raspberry jam. Which statement is true about the cost to make a container of the strawberry jam?

The cost to make a container of the strawberry jam was $3.10 in the year the company opened, and the cost increased by $0.05 each year.

The cost to make a container of the strawberry jam was $0.05 in the year the company opened, and the cost increased $3.10 each year.

The cost to make a container of the strawberry jam was $3.10 in the year the company, and the cost increased 5 percent each year.

The cost to make a container of the strawberry jam was $0.05 in the year the company opened, and the cost increased 3.1 percent each year.

What does g(4) = 3.04 represent in this context?

The cost to make a container of the grape jam in year 4 after the company opened was $3.04.

The cost to make a container of the grape jam in year 3 after the company opened was $3.04.

The cost to make a container of the grape jam in year 3 after the company opened was $4.00.
