La pieza rectangular de tela en cada rollo mide 2.5 pies por 15 pies si el area de la cortina es de 200 pies cuadrados cual es la menor cantidad de rollos que necrsitan?

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
