Rewrite the given equation as 
y=x^2-4x+8=x^2-4x+4+4=(x-2)^2+4.
Since (x-2)^2\ge 0, you can conclude that the imimum value of y will be gained for the minimum value of (x-2)^2. The minimum value of (x-2)^2 is 0 for x=2. 
So, y(2)=0+4=4.
Answer: minimum value of y is 4, when x=2.

Its same as powers of a whole number.

Ok so Jesse is 10-15%
Margie is <10%
Pietro is >15%
Susana is 10%-15%
And I think Raul maybe >15%

Basically you can determine how far off they are by doing the number they guessed divided by the actual number (132) so for Jesse I did 120/132 and I got .909 and so on. Just take the two numbers after the decimal and that’s your percent. So the .909 is about 90% so now do 100% (of the 132) - 90 and you get 10. So I put 10%-15%
