C (third graph, the parabola); To find if it is a function or not draw a vertical line on the graph. If the vertical line could never intercept the figure more than once anywhere on the graph then it is a function.
Should be 59.490 just because if you have to round the tenth and the hundredth together

meaning 2.5 pounds is added to the skull, 602.5 pounds.
70/2 = 35
The car gets 35 miles per gallons.
You can also find that out by looking at the slope of the equation. y = 35x. 35 is the slope here.
For your graph, plot the points:
(0,0)
(1,35)
(2,70)
(3,105)
(4,140)
(5,175)
(6,210)
(7,245)
(8,280)
And then draw a line through the points.
