Answer:
Therefore the answer is the fourth option y = f(x) = - 8x + 13
Therefore when x = 4 then y = -3 from the equation of parabola and this is the required vertex.
Step-by-step explanation:
i) f(x) = + 8x + 19 =
+ 3. SO the vertex is at (-4, 3)
Therefore the answer is the fourth option y = f(x) = - 8x + 13
= ( - 8x + 16) + 3 =
- 3
Therefore when x = 4 then y = -3 from the equation of parabola and this is the required vertex.
