3) Expresa mediante una fórmula la función que a un número entero x le hace corresponder el doble del número siguiente a x. Haz una tabla con algunos valores.

The function is: f(x) = 2*(x +1)

Step-by-step explanation:

This can be translated to:

"write an equation of a function where a whole number x corresponds to the next number to x"

the next whole number to x is x+1., and we want the double of that.

Then we have that our function is:

f(x) = 2*(x +1)

Now we can do a little table of it:

f(0) = 2*(0 + 1) = 2

f(1) = 2*(1 + 1) = 4

f(2) = 2*(2+ 1) = 6

. Véase explicación.

Step-by-step explanation:

La expresión de la función citada es:

Algunos valores se presentan a continuación:

x                y

-2              -2

-1                0

0               2

 1               4

 2              6

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
