1) f(x) = x 2 − 6x + 5

2) f(x) = −4x − x
2 − 4

1) identificando el vértice de cada función utilizando la fórmula.
2) Construir una tabla de valores y debes realizar todos los cálculos en tu cuaderno
para obtener los puntos que forman la parábola (con 7 puntos).
3) Graficar en tu cuaderno cada función cuadrática utilizando regla para trazar los ejes
coordenados, lápiz grafito y goma. Trata de esbozar la gráfica con el mejor pulso
posible (los puntos de la función no se unen con regla)
4) Señalar la intersección de la parábola con los ejes coordenados.
5) Señalar la naturaleza de cada función cuadrática.

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
