Aquadratic function has these characteristics:
x = 1 is the equation for the axis of symmetry.
x = –1 is an x-intercept.
y = –4 is the minimum value.
determine the y-intercept of this parabola.

explain your thought process.

The y-intercept would be between 0 and -4 likely about -3.

Step-by-step explanation:

The y-intercept would be between 0 and -4 likely about -3.

Since the parabola has an axis of symmetry at x = 1 and a minimum of y = -4 then the vertex is (1,-4).

It has an x-intercept at x = -1 or (-1,0). This means from the vertex up to the x-intercept the function has to cross through the y-axis. This makes the y-intercept between 0 and -4 and likely at -3.
