How do you find the x-intercepts of this function parabola?
NikaRhythmics
Solve the quadratic equation.
If y = ax^2+bx+c then the intercepts are
x = [-b +/- sqrt(b^2 - 4ac)]/(2a).
The solutions are real if and only if b^2 >= 4ac

Is a parabola a function?
Y = X2 ===== The graph of this parabola is crossed only at a point and once by a vertical line, so it is a function. Passes the vertical line test.
Can a parabola represent a function?
If a vertical line passes through the supposed function at only one spot then you have a function.

How do you tell if a quadratic function is minimum value or a maximum vale?
Standard notation for a quadratic function: y= ax2 + bx + c which forms a parabola, a is positive , minimum value (parabola opens upwards on an x-y graph) a is negative, maximum value (parabola opens downward) See related link.
How do you find the endpoints of a parabola when you have the function of the line?

Why is any parabola that opens upward or downward a function?
It is a function because for every point on the horizontal axis, the parabola identified one and only one point in the vertical direction.
