That is, a path exists from the first vertex in the pair to the second, and another path exists from the second vertex to the first. What is a weak graph?
What is the leading coefficient of a graph?
Space and AstronomyA leading coefficient is the coefficient preceding the term with the largest exponent. The direction of a graph is determined by whether the leading coefficient is positive or negative, and the width or steepness of a graph is determined by how large or small the leading coefficient is. How do you find the leading coefficient
