Me identify the vertex & explain what method you used

(-2, 4)

Step-by-step explanation:

The given equation is already in vertex form: y = a(x - h)² + k    where

Therefore, y = (x - 2)² + 4    ⇒   (h, k) = (2, 4)

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

70,000 + 6,000 + 800 + 30
