The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.
Since the range has less than a sign, this means that the parabola is
facing downwards and it means that a is negative.
The range is given by

<h3>What is the vertex form of a
quadratic equation?</h3>

Since the range is

This means that k = 5 , and since a is negative
The correct function is
