7. Completa el enunciado Si el precio de los combustibles ha bajado entonces, vamos a impulsar las energías alternativas y cuando las energías alternativas sean impulsadas entonces se lograra que los precios de los c0ombustinbles suban. Si a las dos primeras proposiciones simples (1. Precio de los combustibles, ha bajado. 2. Vamos a impulsar las energías alternativas) que juntos forman la primera proposicion compuesta se considera como verdaderas el valor de verdad de la segunda proposición compuesta es y el valor de verdad de toda la propuesta es .
1. Falsa – falsa
2. Falsa - verdadera
3. Verdadera – falsa
4. Verdadera – verdadera

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
