What is c in a parabola?

It is a constant that determines the y-coordinate of the point at which the parabola crosses the y-axis.


What are the zeros of a parabola?

They are the x-values (if any) of the points at which the y-value of the equation representing a parabola is 0. These are the points at which the parabola crosses the x-axis.

When does a parabola always cross the x-axis twice?

If the equation of the parabola is represented byy = ax^2 + bx + c then it crosses the x-axis twice if and only if b^2 > 4ac


What is the average of the two roots of quadratic equation?

In a quadratic y = ax² + bx + c, the roots are where y = 0, and the parabola crosses the x-axis. The average of these two roots is the x coordinate of the vertex of the parabola.


Does a parabola always have roots and a vertex?

Yes, a parabola always has a vertex. However, it may not always have roots. The roots of a parabola are the x-values where the parabola intersects the x-axis. It is possible for a parabola to have two, one, or no roots depending on the discriminant of the quadratic equation.


What is the value of the coordinate of every point on the xaxis?

It is called the ordinate.


Where do you find the roots when looking at a parabola?

-- The roots of a quadratic equation are the values of 'x' that make y=0 . -- When you graph a quadratic equation, the graph is a parabola. -- The points on the parabola where y=0 are the points where it crosses the x-axis. -- If it doesn't cross the x-axis, then the roots are complex or pure imaginary, and you can't see them on a graph.


What does an X-intercept look like?

On a graph it is where a point on a line/parabola/hyperbola/... Crosses the x-axis. And it can also be in parenthesis when written out. For example: (3,0)


What is a parabola and quadratic?

A parabola is a line with one curve, that usually crosses the x-axis of a graph twice (unless the roots are imaginary). To find the roots, set y to zero and use the quadratic formula (-b±√b^2-4AC/2A)


What is y equals -x2 plus 4?

This is a parabola pointing 'down'. It's apex is at the point (4,0). It crosses the x-axis at the points (2,0) and (-2,0)


When your independent variable is plotted on the xaxis and the dependent variable is plotted on the yaxis?

.... then your graph is inverted.
