# How to write a function notation equation

Linear functions are very much like linear equations, the only difference is you are using function notation "f x " instead of "y". Otherwise, the process is the same. Ok, let's move on! Another thing to notice is the sets O nc and O cn are very different. If c is greater than one, then the latter grows much faster.

A function that grows faster than nc for any c is called superpolynomial. One that grows more slowly than any exponential function of the form cn is called subexponential. An algorithm can require time that is both superpolynomial and subexponential; examples of this include the fastest known algorithms for integer factorization and the function nlog n.

We may ignore any powers of n inside of the logarithms. The set O log n is exactly the same as O log nc. Similarly, logs with different constant bases are equivalent. On the other hand, exponentials with different bases are not of the same order. For example, 2n and 3n are not of the same order.

Changing units may or may not affect the order of the resulting algorithm. Changing units is equivalent to multiplying the appropriate variable by a constant wherever it appears.

For example, if an algorithm runs in the order of n2, replacing n by cn means the algorithm runs in the order of c2n2, and the big O notation ignores the constant c2. This is not equivalent to 2n in general. Changing variables may also affect the order of the resulting algorithm.lets say you have to write 5x+6y= in function form.

when you are writing an equation in function form, you usually solve for f(x) or g(x), but in. Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity.

It is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation.. In computer science, big O notation is used to classify algorithms. SOLUTION: Write each equation in function notation. Solve the equation for y and then replace y by f(x).

(Paul Adrian Maurice) Dirac created a powerful and concise formalism for it which is now referred to as Dirac notation . f(x) "f(x) = " is the classic way of writing a function.
