Extracted text: (3) (i) A broken pipe at an oil rig off the east coast of Trinidad produces a circular oil slick that is S meters thick at a distance x meters from the break. It difficult to measure the thickness of the slick directly at the source owing to excess turbulence, but for x>0 they know that 5 + 3 S(x) = x' +x + 2x If the oil slick is assumed to be continuously distributed, how thick is expected to be at the source? 4x +7 1<><2 (ii)="" if="" ƒ(x)="">< 4х?="" -="" 1="" determine="" whether="" the="" function="" f(x)="" is="" continuous=""><><4 throughout="" its="">
