Hello there! :D
6 in' pieces can be cut! :D
Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
15.5, because 31 divided by 2 is 15.5. And all the other number divided by the number below them also turns out to be 15.5.
Hope this helps. :)
