Answer : f(x) < = 1
From the graph we can see that the vertex is (4,1)
x= 4 and y =1
The maximum point on the graph of the absolute function is (4,1)
for range we look at the y values on graph
The graph start at y=1 and goes below 1
Since the graph goes down, we use <= symbol
The maximum point on y starts at 1 and does down to infinity
so f(x) < = 1
