the function of y= x^2 - 4x + 8 approximates the height y, of a bird and its horizontal distance, x as it flies from one fence p
Vika [28.1K]
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.
