Answer:

(-2, 8)

Step-by-step explanation:

For the function f(x) = ax² + bx + c

Vertex is found by:

  • x = -b/(2a)

For the given function

  • f(x)=x² + 4x + 12

Vertex is:

  • x = -4/2 = -2

And the minimum value is:

  • f(-2) = (-2)² + 4(-2) + 12 = 4 - 8 + 12 = 8

So the coordinates of vertex is (-2, 8)
