Question

determine the domain on which the following function is increasing.
swer attempt 1 out of 2

Explanation:

Step1: Identify vertex x-coordinate

The parabola's vertex (peak) is at $x=2$.

Step2: Find increasing interval

A downward-opening parabola increases left of its vertex. So the interval is all $x$ less than 2, written as $(-\infty, 2)$.

Answer:

$(-\infty, 2)$
