Answer:

See below

Explanation:

I assume you mean
f(x) = 3(x-1)^2-4

The equation is already in vertex form
f(x)=a(x-h)^2+k where
a affects how "fat" or "skinny" the parabola is and
(h,k) is the vertex. Therefore, the vertex is
(h,k)\rightarrow(1,-4).

The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as
x=h for a parabola with a vertical axis. Hence, the axis of symmetry is
x=1.

The minimum value is the smallest value in the range of the function. In the case of a parabola, the y-coordinate of the vertex is the minimum value. Therefore, the minimum value is
y=-4.

The interval where the function is decreasing is
(-\infty,1)

The interval where the function is increasing is
(1,\infty)
