From the graph of the function f(x) we have:
When f(x)=0 , x= -1.8
By looking at the graph we observe that the graph first increases in the interval (-∞,-1.2) and then it decreases in the interval (-1.2,0.6) and then again it increases in the interval (0.6,∞).
Hence, the graph of the function is neither strictly increasing nor strictly decreasing in the whole of the real line.
Also, when x=0 the value of the function is: f(x)=5
( Since, the graph passes through the point (0,5) )
Also, when f(x)=0
then x= -1.8
( Since, the graph of the function passes through the point (-1.8,0) )
