A function, in mathematics, is used to indicate the relationship between two or more quantities. For example, the term function can be used to designate a power xn of a variable x. In addition, it can be applied to various geometric aspects of a curve, such as its slope. The concept of a function is also related to the Dirichlet concept. Dirichlet regarded y = x2 - 3x + 5 as a function which is thought of as …showed first 75 words of 2259 total…

For problems involving constant gravitational pull on objects in free fall the equation y (t) = -1/2gt2 + v0t + y0.
