Does a vending machine represent a function and why?

1 answer:

4 0

Sure, depending on how the machine is constructed or programmed.

A function can represent any process that takes some input and assigns exactly one output to it. In the case of a simple vending machine, there could one button or sequence of button presses that correspond to the delivery of a certain drink or snack (provided that enough money is fed into the machine first).

A machine that wouldn't qualify as representing a function would be one that consistently offers two or more different drinks.

Consider the exponential functions below.

klio [65]

The functions in order from least to greatest according to their average rates of change are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

<h3>How to order the functions?</h3>

The rate of change is calculated using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

For function g at the interval [2,3], we have:

$m = \frac{g(3) - g(2)}{3- 2}$

This gives

$m = \frac{20 - 4}{3- 2}$

$m =16$

For function h at the interval [0,2], we have:

$m = \frac{h(2) - h(0)}{2- 0}$

Where:

h(2) = 3(3)^2 - 9 = 18

h(0) = 3(3)^0 - 9 = -6

This gives

$m = \frac{18 + 6}{2 - 0}$

$m = 12$

For function f at the interval [1,2], we have:

$m = \frac{f(2) - f(1)}{2- 1}$

This gives

$m = \frac{12 - 6}{2 - 1}$

$m = 6$

Hence, the functions are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

Simplify 2x – 9y + 4x + 11y by combining like terms and then evaluate at x = -2<br> and y = 4.

Mashcka [7]

Step-by-step explanation:

= 2x - 9y + 4x + 11y

First of all combining like terms

= 2x + 4x - 9y + 11y

= 6x + 2y

Now putting values

= 6 (-2) + 2(4)

= - 12 + 8

= - 4
