Step-by-step explanation:
Answer:
- y = 3(x -3)^2 +1
- y = 3x^2 -18x +28
Step-by-step explanation:
For vertex (h, k) and vertical scale factor "a", the vertex form of the equation of a parabola is ...
y = a(x -h)^2 +k
For (h, k) = (3, 1) and a = 3, the equation in vertex form is ...
y = 3(x -3)^2 +1
__
Expanding this gives the equation in standard form.
y = 3(x^2 -6x +9) +1
y = 3x^2 -18x +28
