Answer:
First, second, third, and fourth are functions
Step-by-step explanation:
Each input in the first, second, third, and fourth only have one output. In the fifth one 3.3 and 6.6 are seen twice as the x-value, so this is incorrect.
(answered this on your other question, but I will put it here too!)
Cada entrada en la primera, segunda, tercera y cuarta tiene solo una salida. En el quinto, 3.3 y 6.6 se ven dos veces como el valor de x, por lo que esto es incorrecto.

Answer:
Huh I don’t understand this one but I got you
Step-by-step explanation:
Answer:
Step-by-step explanation:
it's 2ab + c^ 2
why?, well, we can change the position of the 2 triangle in each corners into this (in the picture below) :
you can see that a^2 + b^2 = c^2
then there are 2 ab from 4 triangles we add that create 2 rectangle then we multiply each rectangles by its sides
so , c^ 2+ 2ab is the answer

hope this is helpul!
Answer:
A
Step-by-step explanation:
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
