👉 Graphy is a term used in mathematics to describe the relationship between two variables. In other words, it refers to the plot of a function or curve on a Cartesian plane, which represents how one variable changes as another variable varies. For example: - If we have a function y = x^2 + 3x - 4, this is a graph of y against x. - If we have a function f(x) = x^3 - 5x^2 + 6
