Question

A parabola opens down and its vertex is (2, 5). What is the range of this function?

Answer 1

The range of the parabola that opens down and has its vertex as (2, 5) is (b) $(-\infty,5]$

Vertex

The vertex of a parabola can represent the minimum or the maximum point in the parabola

The vertex of the parabola is given as:

$(h,k) = (2,5)$

The range

The range of a function is the set of output values the function can take

From the question, we understand that the parabola opens down.

This means that, the vertex of the parabola is a maximum.

Hence, the range of the parabola is $(-\infty,5]$
