how to build functions math help

Laura is building rectangular boxes of different sizes. The length of the box ' y ' is 8 times its width ' x '. If the widths she is using are 5 cm, 7 cm and 9 cm, then choose a rule for the relation between the length and the width and determine if this relation is a function. ..

The basic building blocks for a complex digital system are known as logic gates. A gate is a simple electronic circuit or device that performs logical functions. It has one or more inputs and one output gate and are also called binary logic gates, as 1 and 0 are the inputs and ..

Function - Any relation on A x B in which (i) no two second elements have a common first element and (ii) every first element has a corresponding second element is called a function.Any relation on A x B in which (i) no two second elements have a common first element and (ii) ev..

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..

So far, we know how to differentiate functions like sin x and x 3 - 5. But how do we differentiate a function of a function? That is how can we differentiate sin (x 3 - 5)?So far, we know how to differentiate functions ..

Which of the following functions is not an exponential function? => y = 4 x or y = ( 1 / 7 ) x or y = 5 - x or y = (- 6 / 5 ) x..
