Answer:
See below
Step-by-step explanation:
I assume you mean
The equation is already in vertex form where affects how "fat" or "skinny" the parabola is and is the vertex. Therefore, the vertex is .
The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as for a parabola with a vertical axis. Hence, the axis of symmetry is .
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 .
The interval where the function is decreasing is
The interval where the function is increasing is
