Question 734571: a quadratic function has the following 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 the parabola

The axis of symmetry and the minimum value give you the vertex, (1, -4) = (h, k). You can begin developing an equation as .
Could you try to use the given x intercept to solve for and find the value for "a"? You would then have the equation for this parabola. Let x=0 and find y.
How does this work: x intercept is at -1.
.
Parabola is . y intercept would be at x=0.
