As there is a repeated x-coordinate, x = f(y), giving:As it is a parabola, x = ay² + by + c, so substituting the known points:(0, 0) → 0 = 0²x + 0b + c → 0 = c(20, 12) → 20 = 12²a + 12b + c → 20 = 144a + 12b + c(0, 40) → 0 = 40²a + 40b + c → 0 = 1600a + 40b + cFrom equation 1, c = 0, so substituting in the second and third equations gives two new equations involving two unknowns:20 = 144a + 12b0 = 1600a + 40bThe second of these can be simplified to give: 0 = 40a + b→ b = -40aThis can be substituted back into the first to give:20 = 144a + 12 b→ 20 = 144a + 12(-40a)→ 20 = 144a - 480a→ 20 = -336a→ a = -5/84→ b = -40a = -40(-5/84) = 50/21→ x = -5/84 y² + 50/21 y→ 84x = -5y² + 200y→ 84x = 200y - 5y²The parabola has equation 84x = 200y - 5y²
