Respuesta :

The maximum or minimum of a quadratic function is also its y-value in the vertex. You can identify it in a quadratic funcion written is vertex form:

[tex]f(x)=a(x-h)^2+k[/tex]

The k is the maximum or minimum value.

For the given functions the one that reveals the minimum or maximum value is:

[tex]f(x)=3(x-8)^2+1[/tex]

Maximum or minimum value: 1
