Question

If the vertex of the graph of y = −1(x − 2)2 + 3 is (a,b) what is the value of b?​

Answer 1

b=3

Explanation:

`y=a(x-h)^2+k\\y=-1(x-2)^2+3`

If we compare the vertex-form equation of a parabola to our given function, we can see the vertex is
`(2,3)`, which means that b=3.

Answer 2

the value of b is 3.

Explanation:

The vertex of the graph of a parabola in the form y = a(x - h)^2 + k is given by (h, k), where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.

So in this case, the vertex of the graph of y = -1(x - 2)^2 + 3 is (2, 3), and the value of b is 3.
