Question 10 (1 point) What is the equation of the parabola with vertex (1, -11) and that passes through (- 4, 64)? Of(x) = - 3x2 + 6x - 14 ORx) = (x-1)3 - 11 Of(x) = 3(x + 1)2 - 11 O Ax) = 3x2 - 6x - 8 Question 11 (1 point) Maria is installing a small pond in her garden. The pond will be in the shape of a semicircle. The curve of the pond has a shape that can be modelled by the equation of a parabola. If the edge of the pond is the origin and the pond is 8 m wide at its widest, what is the equation of the parabola if the height (from bottom to top) of the pond 3 m from the bottom is 5 m? Of(x) = - 3(x - 8)3 O Ax) = - -x(x - 8) O Ax) = 8(x - 3)2 + 5 Ofx ) = =x(x +8)Question 12 (1 point) What is the equation of the parabola with vertex (-3, 8) and that passes through (-7, 13)? -5 2_ 15 701 82 O Rx) = 2(x + 3)3 + 8 ORx ) - 1627 + 173 16 Ofx ) = 10 5 ( 2 + 3 ) 2 + 8 Question 13 (1 point) What is the equation of the parabola with x-intercepts 1 and 3, and that passes through (-1, 16)? ORx) = 2(x - 1)2 + 3 O Ax ) = x3 +4x +3 Of(x) = 2x2 - 8x +6 ORx) = -x3 + X+ 16
