What is the vertex of the quadratic function f(x)=3(x-5)^2+4???

Vertex: (5, 4)

Step-by-step explanation:

Quadratic Transformations Equation: f(x) = a(bx - h)² + k

a - vertical shrink/stretch

b - horizontal shrink/stretch

h - horizontal movement left/right

k - vertical movement up/down

h, k - vertex
