Answer:
a) 1.
Step-by-step explanation:
Supongamos que el primer número entero positivo es a tal que a ∈ Z⁺.
Luego, el conjunto de los cinco enteros positivos se puede expresar como
A = {a; a+1; a+2; a+3; a+4}
Dada la condición del problema, se debe cumplir que
a + (a+1) + (a+2) = (a+3) + (a+4)
⇒ 3a + 3 = 2a + 7
Resolviendo la ecuación resulta
a = 4
Luego, el conjunto A nos resulta
A = {4; 5; 6; 7; 8}
Puede concluirse que sólo un conjunto cumple con esta condición.
Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):

You need to:
Substitute
into the function:

Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:

Now, replace "x" with "y" and replace "y" with "x":

Therefore, substituting
you get:
or
