t ≥ 72
Step-by-step explanation:
The pool has to be at least 72° or MORE to open, so we are going to have a greater sign with an equal sign under indicating that the temperature has to at least be 72° or be greater than 72°. (≥)
6446(7546/6799/)85456=gljdhsshdjkhk ghjvf 146
-4f+8=4f-8
+4f. +4f
8=8f-8
+8. +8
16=8f
16/8=2
f=2

The function is not linear because the graph is not a straight line.
A linear function has a graph that is a straight line; the rate of change is the same between consecutive points.
In this graph, the rate of change is different between different pairs of points. This is a parabola; this is not a linear function.
