Which point is the vertex of the quadratic function f(x)=(x-4)^2+3 a (3, 4) b (3, -4) c (-4, 3) d (4, 3)

Answer:
D
Step-by-step explanation:
To find the x coordinate of the vertex, we look at the quadratic given (which is conveniently already in vertex form). We see that there is a term. The inside (x - 4) indicates where the x coordinate is. Since it is x - 4 and not x + 4, we know that the x coordinate will be positive 4 (because things are a little backward for x).
To find the y coordinate of the vertex, we look at the + 3 term at the end. The number here will indicate what the y coordinate is. Since it is + 3, and not - 3, we know that the y coordinate will be positive 3 (because things are NOT backward for y).
Thus, the vertex is D, (4, 3).
Hope this helps!

Step-by-step explanation:
According to the U.S. Census Bureau, the legal official department in charge of the National Census every ten years, the population of the U.S.A in 2010 was<em> 308,745,538 inhabitants.</em>
If about 25,585,000 had diabetes, then <em>cross multiplying</em>
308,745,538-------100%
25,585,000---------x%
and
and so, about
Americans had diabetes in 2010.
