Answer is C because if swimmer A does 14 laps to start an 3 laps every day after that and on the chart swimmer B does 11 laps to start and 2 laps every day after that you would compare.
on day 3 swimmer B has 17 (shown on chart)
on day 3 swimmer A has 23 (14, 17, 20, 23)
if you would want it to complicate it 14:3 and 11:2
Hello : <span>the parabola's equation is : f(x) = a(x+3)²-1 </span><span>the coefficient of the squared expression in the parabola's equation is : a but ; f(4) = 0 0 = a(4+3)²-1 49a-1=0.....a=1/49 f(x) = 1/49(x-3)²-2</span>
