Answer:


f(x)=-(x-4)^2+5

Explanation:

The function
f(x)=-(x-4)^2+5 has the vertex at
(4,5).


Since
a=-1\:<\:0, the graph of the function is a maximum graph.


The highest y-value is the y-coordinate of the vertex which is 5.


Therefore the range is {
y|y\le 5}


Therefore the correct answer is B.


hich function has a range of y ≤ 5? f(x) = (x – 4)2 + 5 f(x) = –(x – 4)2 + 5 f(x) = (x-example-1
