Agarden is the shape of a rectangle, abcd and a semicircle. ad is the diameter of the semi-circle. carol is going to cover the garden with fertiliser.
a box of fertiliser costs £4.99
carol has been told that one box of fertiliser will cover 12m^2 of the garden
(a) work out the cost of buying enough fertiliser to cover the garden completely

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
