how to write function rules

Write a rule for the linear function in the table. => f ( x ) = 4 x - 1 or f ( x ) = 2 x + 3 or f ( x ) = 3 x + 1 or None of the above..

The graph shows the relationship between distance and time for a truck driven at a constant speed. Make a table for the function and write a rule to represent the function. => Distance = 15 + time or Distance = 15 × Time or Distance = 5 × Time or ..

A telephone company charges $24 as monthly rent and 70 cents per call. Write a function rule for the total monthly bill for a telephone connection. => f ( x ) = 24 + 0.7 x or f ( x ) = 24 + 70 x or f ( x ) = 24 + 7.0 x or None of the above..

A fruit seller sold fruits and earned a profit of 13% on the cost price. Write a function rule for the selling price of the fruits. => f( x ) = x - 0.13 x or f( x ) = x + 13 x or f( x ) = x + 0.13 x or None of the above..

Frank works as a sales person. He earns a salary of $425 and 4% commission on his monthly sales. Write a function rule that relates his total earnings to sales and find his earnings for the month, if his monthly sales are $4000. => $600 or $585 or $575 or $745..

Rules for Writing Equilibrium Constant Expressions - Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to its stoichi..

Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to its stoichiometric coefficient in the balanced chemical equation, and the deno..

Function - We consider two sets A and B. We form the Cartesian Product, we form relations. From all the relations, we can select a few which satisfy the rule that each element of the set A is related to only one element of the set B. When a relation satisfies this rule..

Let A and B be two non-empty sets.Let A and B be two non-empty sets. A function f from A to B is an association of every element of A to an unique element in B. We write this as f : A g B. A is called the domain. B is called the co-doma..

Which of the following rules represents the linear function graph? => f(x) = -2x + 2 or f(x) = 2x + 2 or f(x) = -1 2 x + 2 or f(x) = 1 2 x + 2..
