## What other situations between two variables in everyday life can be described as a function

In the case of tossing a ball in the air, time is the input and height is the output. With the cars and wheels, the answer is yes. Circumference of a circle is a function of diameter. Quadratics in Athletics In athletic events that involve throwing objects like the shot put, balls or javelin, quadratic equations become highly useful. Here there are two variables: your salary and the amount you spend. We all know that it takes time to travel distances and when we travel any distance or stand still , it takes a certain amount of time to do so. Basic economics and money math: A weekly salary is a function of the hourly pay rate and the number of hours worked. Among the most important algebraic relations are functions. Graphing Dependent and Independent Variables In both math and science, dependent and independent variables can be plotted on the x and y axes of a graph. The final solution of the equation, y, depends on the value of x, the independent variable which can be changed.

There is a one to one correspondence. Every single car has 4 tires, so the number of tires depends on how many cars are in the parking lot.

The standards overview for grades expects the understanding that "in the 'real-world,' functions are mathematical representations of many input-output situations.

An input is the independent, non-repeating quantity. Here there are two variables: your salary and the amount you spend.

In other words the parenthesis does not mean that f is multiplied by x. Expressions such as 4x3 which consists of a coefficient times a variable raised to a power are called monomials.

## Application of function in daily life

It tries to give the relationship a mathematical form. The more one smokes cigarettes, the fewer years she will have to live. Functions with more than one independent variable are called multivariate functions. Which of the following situations describes a function? Finding a Speed Quadratic equations are also useful in calculating speeds. If diameter is the input and circumference is the output, what's the function rule? For an input of 25 cars we always get an output of tires, no matter which 25 cars drive into that parking lot or when they arrive. Because a single address can produce more than one set of occupants, the relation is not a function. In the above example the degrees of the terms are 5, 3, and 0.

The relation is a function. Find f 0.
