    y=1/∛4 divides the area in half

    Step-by-step explanation:

    since the minimum value of x² is 0 (for x=0) and for y=1

    1 = 25*x² → x = ±√ (1/25) = ±1/5

    then the total area between y=1 and y = 25*x² is bounded to x=±1/5 and y=0. Since there is a direct relationship between x and y, we can find the value of x=a that divides the region in 2 of the same area. thus

    Area below x=C = Area above x=C

    Area below x=C = Total area - Area below x=C

    2*Area below x=C = Total area

    Area below x=C = Total area / 2

    ∫ 25*x² dx from x=c to x=-c = 1/2 ∫ 25*x² dx from x=1/5 to x=-1/5

    25*[c³/3 - (-c) ³/3] = 25/2 * [ (1/5) ³/3 - (-1/5) ³/3]

    2*c³/3 = (1/5) ³/3

    c = 1 / (5*∛2)

    thus

    y=25 * x² = 25*[1 / (5*∛2) ]² = 1/∛4

    thus the line y=1/∛4 divides the area in half
