A quadratic 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.
