By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.

That gives us point (3,5) as the top of the parabola. So there you go, answer A.

The coordinates of the vertex of the parabola is (3,5).

What is coordinate geometry?

'In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.'

According to the given problem,

Given equation:

y = -4(x - 3)² + 5

m = -4

c = 5

The coordinates of the vertex of the curve is (3 , 5).

Hence, we can conclude, the coordinates of the vertex of the parabola is (3 , 5).
