Which could be the function graphed below?

On a coordinate plane, a curve opens down and to the right in quadrants 1 and 4. The curve starts on the y-axis in quadrant 4 and goes through the x-axis into quadrant 1.
f (x) = StartRoot x EndRoot minus 2
f (x) = StartRoot x minus 3 EndRoot + 1
f (x) = StartRoot 2x + 4 EndRoot
f (x) = StartRoot x + 1 EndRoot + 8

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
