As is the case for any polynomial, the domain of this one is (-infinity, +infinity).
To find the range, we need to determine the minimum value that f(x) can have. The coefficients here are a=2, b=6 and c = 2,
The x-coordinate of the vertex is x = -b/(2a), which here is x = -6/4 = -3/2.
Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on. That happens to be y = -5/2, so the range is [-5/2, infinity).
Answer:
2hms+2hns
Step-by-step explanation:
The lower end of the range is
42.670 - 0.002 = 42.668 mm
The upper end of the range is
42.670 + 0.002 = 42.672 mm
The range of acceptable values is 42.668 mm to 42.672 mm.
So when you are trying to tell the difference between something, you need to find the difference through subtraction! 6 1/6 - 4 5/6 = 1 1/3. :) I hope this helps!
