Answer:
A. (4,3)
Step-by-step explanation:
The vertex of a parabola is the maximum or minimum point on the graph of the quadratic function aka where you just have "one value" wether than be the very top, the very bottom, etc
In summary:
Here we can see it'll be the very bottom as the parabola is angled upwards.
Looking at the graph, we can see it is 4 units to the right and 3 units up.
The first number is the x, or the right/left, so our first number is 4
The second number is our y, or the up/down, so our second number is 3
This leaves us with the point (4, 3) and an answer of A!
Hope this helps, have a nice day :D
