Answer:
Linear non-linear
x<2 , x>5 2<x<5
Step-by-step explanation:
When a function is linear then the graph is a straight line
When the function is not linear then the graph is like a curve
From x = - infinity to 2 the graph is a straight line
So from - infinity to 2, the function is linear, that is x<2 function is linear
from 2 to 5 the graph is like a curve , so it is not linear
2<x<5 , the function is not linear
From x = 5 to infinity the graph is a straight line
So from 5 to infinity, the function is linear, that is x>5 function is linear
