Y=-1/4(x- - 2)^2+ 4

You can see it take shape by drawing it out. Then shift x left by 2 (-2) and up 4 (+4) . A trick for the slope is that by looking at .75 you know it has to be some fraction with a even denominator.

Given f(x)= -4x+7, find f(1)
Lisa [10]
Hi there!

To find f(1), plug in x=1 into the equation

= -4 + 7
= 3
That's your answer.

Que forma tiene un hexágono y como se entre si?
Mars2501 [29]

Answer:

Al igual que los cuadrados y los triángulos equiláteros, los hexágonos regulares encajan sin ningún espacio para enlosar el plano (tres hexágonos se encuentran en cada vértice), por lo que son útiles para construir mosaicos.
