Answer:
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Step-by-step explanation:
i) f(x) = -(x+9)(x-21)
ii) therefore y = f(x) = - + 12x + 189 = - (
- 12x +36) + 36 + 189
iii) therefore y = f(x) = - + 225
iv) when x = 6 then y = 255
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
