Question

Where do the roots of a quadratic function exist on a graph and what is the value for the output for all roots?

Answer 1

treat a quadratic equation like a linear one/ plug values of x into the equation plot them and connect the dots through the parabola

Answer 2

Answer:

If the graph of the quadratic function y = a x 2 + b x + c crosses the -axis, the values of at the crossing points are the roots or solutions of the equation. If the equation a x 2 + b x + c = 0 has just one solution (a repeated root) then the graph just touches the -axis without crossing it.
